  • Ops Center 12c - Update - Provisioning Solaris on x86 Using a Card-Based NIC

    - by scottdickson
    Last week, I posted a blog describing how to use Ops Center to provision Solaris over the network via a NIC on a card rather than the built-in NIC.  Really, that was all about how to install Solaris on a SPARC system.  This week, we'll look at how to do the same thing for an x86-based server. Really, the overall process is exactly the same, at least for Solaris 11, with only minor updates. We will focus on Solaris 11 for this blog.  Once I verify that the same approach works for Solaris 10, I will provide another update. Booting Solaris 11 on x86 Just as before, in order to configure the server for network boot across a card-based NIC, it is necessary to declare the asset to associate the additional MACs with the server.  You likely will need to access the server console via the ILOM to figure out the MAC and to get a good idea of the network instance number.  The simplest way to find both of these is to start a network boot using the desired NIC and see where it appears in the list of network interfaces and what MAC is used when it tries to boot.  Go to the ILOM for the server.  Reset the server and start the console.  When the BIOS loads, select the boot menu, usually with Ctrl-P.  This will give you a menu of devices to boot from, including all of the NICs.  Select the NIC you want to boot from.  Its position in the list is a good indication of what network number Solaris will give the device. In this case, we want to boot from the 5th interface (GB_4, net4).  Pick it and start the boot processes.  When it starts to boot, you will see the MAC address for the interface Once you have the network instance and the MAC, go through the same process of declaring the asset as in the SPARC case.  This associates the additional network interface with the server.. Creating an OS Provisioning Plan The simplest way to do the boot via an alternate interface on an x86 system is to do a manual boot.  Update the OS provisioning profile as in the SPARC case to reflect the fact that we are booting from a different interface.  Update, in this case, the network boot device to be GB_4/net4, or the device corresponding to your network instance number.  Configure the profile to support manual network boot by checking the box for manual boot in the OS Provisioning profile. Booting the System Once you have created a profile and plan to support booting from the additional NIC, we are ready to install the server. Again, from the ILOM, reset the system and start the console.  When the BIOS loads, select boot from the Boot Menu as above.  Select the network interface from the list as before and start the boot process.  When the grub bootloader loads, the default boot image is the Solaris Text Installer.  On the grub menu, select Automated Installer and Ops Center takes over from there. Lessons The key lesson from all of this is that Ops Center is a valuable tool for provisioning servers whether they are connected via built-in network interfaces or via high-speed NICs on cards.  This is great news for modern datacenters using converged network infrastructures.  The process works for both SPARC and x86 Solaris installations.  And it's easy and repeatable.

  • Iomega eGo Encrypt Plus Encrypted Partition not mounting properly says "local disk"

    - by mosiac
    I'm working with an Iomega eGo 500gb Encrypt Plus portable drive. When I first set it up and installed the software and set a user password everything worked fine. The partition labeled "IomegaHDD" mounted properly and I could access the free space. Then I changed the ADMIN password which required me to lockout the device, wait 60 seconds, and then login to the Admin section and change the password, lockout the device again, wait 60 seconds, and then log back in with my user password. When I did that it of course unmounted the IomegaHDD partition to secure it, when it remounts it, it only shows up as "local disk" now and will not remount properly. I had not removed the cable while doing any of this. I have since tried unplugging and plugging back in to login to the drove but that has not worked. I'm wondering if I should remove every instance of "generic usb hub" from device manager and wait for it to re-add itself, or move it to a new set of USB ports temporarily to seee if that helps. Any ideas?

  • ASP.Net application can no longer write to DB after having run out of disk space

    - by remi.despres-smyth
    I'm a software developer troubleshooting a sticky problem on a client's production server, and I've got a bit of a problem. They have a virtual server running Windows Server 2008, SQL Server 2008 R1 and IIS7. It was provisioned with two partitions: one that has the OS (~15 Gig), and the other has IIS' web sites (another ~15 Gig). My application that's running this server has been running perfectly well, up until about an hour ago, when it started throwing System.IO.IOException: "There is not enough space on disk". As soon as my client notified me, I cleared up some space on C:\, emptied the recycle bin, and restarted SQL Server and IIS. The web server came back up and the application was running, but it no longer saves information to the database. No error message is coming up, the application can get information out of the DB, but it can no longer save data back to it. I rebooted the server, to no effect. I spoke with a sys admin at the hosting company, and he says SQL Server appears to have come up fine and the database is not in read-only mode. I confirmed that, as I can add records to tables from SQL Server Management Studio. I looked at the event log immediately after trying to save an edited record in the app, and no new events appear in there that I can tell. I'm assuming this is related to having run out of space, as it was all working fine prior to that, but I'm at a bit of a loss as to what exactly needs a kick in the pants to get going again. Can anyone help me out? What the heck is going on here?

  • Windows 2003 R2 x86 Mini dump fails to write to disk

    - by Randy K
    I have 3 blade servers that are Blue Screening with a 0xC2 error as far as we can tell randomly. When it started happening I found that the servers weren't set to do provide a dump because they each have 16GB RAM and a 16GB swap file divided over 4 partitions in 4GB files. I set them to provided a small dump file (64K mini dump), but the dump files aren't being written. On start up the server event log is reporting both Event ID 45 "The system could not sucessfully load the crash dump driver." and Event ID 49 "Configuring the Page file for crash dump failed. Make sure there is a page file on the boot partition and that is large enough to contain all physical memory." I understanding is the the small dump shouldn't need a swap file large enough for all physical memory, but the error seems to point to this not being the case. The issue of course is that the max swap file size is 4GB, so this seems to be impossible. Can anyone point me where to go from here?

  • I used disk copy to clone my drive, now my windows 7 profile won't load correctly

    - by RzK
    I used easeuse disk copy, after acronis, clonezilla, windows image restore failed me. Basically it copys all sectors, I set it to skip bad sectors(40). The source drive works, it just gave me a couple errors and stopped booting at one point. The drive is an identical copy, minus 40 bad errors. The drive is set to C and active partition, I rebuilt the boot order. I've ran sfc /scannow and ran chkdsk /r chkdsk found 20kb of bad sectors if I remember right. Now the issue I get is when I log into my profile which was saved right, I get a blank light blue wallpaper (non-license) explorer.exe is not running, and there are only 4 processes running in taskmanager, including taskmanager. I would try a repair install but CRTL-E would not open, nothing will open once I force start explorer.exe, almost like all services are down. What should I do? Fresh install is almost not a possibility I will try and fix this issue. sfc /scannow /offbootdir=c:\ /offwindir=c:\windows returns "Windows Resource Protection could not perform the requested operation"

  • Sharing disk volumes across OpenVZ guests to reduce Package Management Overhead

    - by andyortlieb
    Is it feasible to create a single "master" OpenVZ guest who would only be used for package management, and use something like mount --bind on several other OpenVZ guests sort of trick them into using the environment installed by the master guest? The point of this would be so that users can maintain their own containers, and yet stay in sync with the master development environment, so they'll always have the latest & greatest requirements without worrying too much about system administration. If they need to install their own packages, could put them in /opt, or /usr/local (or set a path to their home directory)? To rephrase, I would like several (developer's, for example) OpenVZ guests whose /bin, /usr (and so on...) actually refer to the same disk location as that of a master OpenVZ guest who can be started up to install and update common packages for the environment to be shared by all of this group of OpenVZ guests. For what it's worth, we're running Debian 6. Edit: I have tried mounting (bind, and readonly) /bin, /lib, /sbin, /usr in this fashion and it refuses to start the containers stating that files are already mounted or otherwise in use: Starting container ... vzquota : (error) Quota on syscall for id 1102: Device or resource busy vzquota : (error) Possible reasons: vzquota : (error) - Container's root is already mounted vzquota : (error) - there are opened files inside Container's private area vzquota : (error) - your current working directory is inside Container's vzquota : (error) private area vzquota : (error) Currently used file(s): /var/lib/vz/private/1102/sbin /var/lib/vz/private/1102/usr /var/lib/vz/private/1102/lib /var/lib/vz/private/1102/bin vzquota on failed [3] If I unmount these four volumes, and start the guest, and then mount them after the guest has started, the guest never sees them mounted.

  • System Center Essentials server running out of disk space due to stored old updates

    - by Ricket
    We have a System Center Essentials (SCE) server to filter updates to our laptops. We've configured it to download the update, and then the laptops get the update from this server; this of course reduces our internet bandwidth and the time it takes for employees to receive the updates, which reduces the complaints we get about how long updates take. However we currently have a total of 2,255 updates stored on the server. SCE gives a breakdown: Updates with installation errors: 29 Updates needed by computers: 280 Updates installed/up-to-date: 0 Updates with no status: 1946 Our little server has 68gb of hard disk space, and the updates are currently taking 32gb and counting. Some of the updates date back to 2003, but we can't figure out a way to delete them to free up space on the server. Right-clicking an update and clicking Uninstall threatens to remove the update from all computers, which is not what we want. Some of the updates even inform us upon viewing: This update has been replaced by a newer update. Before declining this update, it is recommended that you approve the new update first and verify that this update is no longer needed by any computers. How do you prevent your SCE server from filling its hard drive space? Is there a way to configure the server to only keep updates that are still needed? Furthermore, why (in the above breakdown of updates) are there so many updates with "no status" and 0 updates that are "installed/up-to-date"?

  • windows 7: Event 55 The file system structure on the disk is corrupt and unusable

    - by Radio
    Here is a real bad one! Windows 7 RTM with SP1 installed [Version 6.1.7601]. Recently tried to delete some folder on my hard drive and Windows prompted "Error 0x80070570: The file or directory is corrupted and unreadable", and at the same time placed an Event 55 describing "The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on \Device\HarddiskVolume2." Ran chkdsk, first with /f option, then with /r option. Result in both cases was: no errors found, 0 bad sectors. No problems chkdsk found at all! Went through StackExchange, Google and spent over 6 hours on this. Still cannot figure out the problem. Re-installing/Re-Formatting is not an option! What did I try: Hotfix - Windows6.1-KB982927-x64.msu - gave me an error about incompatibility with my computer, however it totally matches my system. CRC of hotfix was ok. Windows Repair Console found startup errors and fixed those, but this didn't help an issue, even by running chkdsk c: /R from it. http://support.microsoft.com/kb/246026 does not promise anything good. sfc /scannow does not help too. Replaced hard drive by cloning an old one using True Image, repeated all steps above. At the same time, some minor glitches started to appear in my Windows, like side panel and notification area settings are getting reset. Goal is to delete the folder and get rid of Event 55. Sounds like NTFS bug. Please help. This is completely ridiculous.

  • How to discover true identity of hard disk?

    - by F21
    I have 2 fake external hard drives that claim to have a storage capacity of 2TB. I pulled the enclosure apart and the hard drives seems to be refurbished ones with their labels replaced as Barracuda LP 2000 GB labels (the serial numbers on both labels are the same). Interestingly, one of the drives have 160G written on it with pencil. However, the counterfeiters seem to have done something to the firmware, because CrystalDiskInfo reports them as 2TB ST2000DL003 drives. I then delete the 1.81 TB partition in Windows disk management and tried to create a new one and format it. Once I get to this point, the drives would make some noise that is common to dying drives. I am not interested in using these drives for production, but I am interested in finding the true identity (manufacturer/serial number/model number, etc) and restoring it to their factory defaults with the right capacity. Can this be done without any special equipment? This would be an interesting learning exercise. Some pictures of the drives in question: Here are the screens from CrystalDiskInfo: Note the serial numbers are the same (these are 2 different drives!). How is this done? Did they have to tamper with the controller board? I would assume that changing the firmware doesn't change the serial number at all.

  • Optimizing Disk I/O & RAID on Windows SQL Server 2005

    - by David
    I've been monitoring our SQL server for a while, and have noticed that I/O hits 100% every so often using Task Manager and Perfmon. I have normally been able to correlate this spike with SUSPENDED processes in SQL Server Management when I execute "exec sp_who2". The RAID controller is controlled by LSI MegaRAID Storage Manager. We have the following setup: System Drive (Windows) on RAID 1 with two 280GB drives SQL is on a RAID 10 (2 mirroed drives of 280GB in two different spans) This is a database that is hammered during the day, but is pretty inactive at night. The DB size is currently about 13GB, and is used by approximately 200 (and growing) users a day. I have a couple of ideas I'm toying around with: Checking for Indexes & reindexing some tables Adding an additional RAID 1 (with 2 new, smaller, HDs) and moving the SQL's Log Data File (LDF) onto the new RAID. For #2, my question is this: Would we really be increasing disk performance (IO) by moving data off of the RAID 10 onto a RAID 1? RAID 10 obviously has better performance than RAID 1. Furthermore, SQL must write to the transaction logs before writing to the database. But on the flip side, we'll be reducing both the size of the disks as well as the amount of data written to the RAID 10, which is where all of the "meat" is - thereby increasing that RAID's performance for read requests. Is there any way to find out what our current limiting factor is? (The drives vs. the RAID Controller)? If the limiting factor is the drives, then maybe adding the additional RAID 1 makes sense. But if the limiting factor is the Controller itself, then I think we're approaching this thing wrong. Finally, are we just wasting our time? Should we instead be focusing our efforts towards #1 (reindexing tables, reducing network latency where possible, etc...)?

  • hp proliant dl360 disk diagnostic issue

    - by user1039384
    We recently got two used drives (15000) and installed on our HP proliant dl360 G5 server. Created RAID1 and used HP SmartStart CD to perform diagnostics. Interestingly, the Diagnostic tab immidiately fails on Logical drive testing saying the Disk1 should be replaced, while the Test tab successfully runs all the complete tests on both disks and does not find any issue. At the meantime, when booting to esxi 5, vSphere periodically shows the Disk1 as Unknown and Logical drive in recovery process. This happens every 5-10 minutes. Here is the log from HP SmartScan diagnostic: 1 - Device, Test: Logical Drive 1, Storage Controller in Slot 0 1 - Description: The controller has reported a critical error in the drive error log. 1 - Recommended Repair: This drive should be replaced. 1 - Failed Count: 44 1 - Error code: F157 There is also another error log record (see below): 2 - Device, Test: test_components/libstorage.so ID 2 - Description: An unexpected exception occurred while performing an operation. Exception message: CISS_StatusHandler::evaluate: commandStatus = 4 (INVALID); hexdump of CISS_ErrorInfo: 00000000: __ __ 04 __ 20 __ __ __ __ __ __ __ __ __ __ __ .... ... ........ 00000010: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........ 00000020: __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ ........ ........

If the problem persists, upgrade to the latest version of Insight Diagnostics. 2 - Failed Count: 48 2 - Error Code: F62 Note that rebooting didn't help and I was running the latest diagnostic software version. Anyone has a clue? Is this a real disk issue? BTW, the controller is Smart Array E200i Thanks in advance

  • Managing disk in a VM

    - by dst
    I'm replacing my two old rack servers with a new one that has plenty of power to take over the functionality my current servers. The server is a 4U rack mount with 16 3.5" SAS drive bays, two 2.5" bays, a Xeon E3-1230v2 CPU and 32GB of ECC RAM. My issue is the following. I would like to have a FreeBSD file server with ZFS managing disks. However, I need other VMs for e.g. a shell/git server, mail server etc. I'm wondering how to deal with the following issues: I want ZFS to fully manage the disks, so I'm not using any hardware RAID. Should I pass the SAS controller directly to the FreeBSD system as passthrough PCI? I want to maximize the reliability of the setup. On what disks should I install the hypervsor and keep server system disks? For (2) I have the option of having a RAID setup on the SAS controller and using that as system disk to store the hypervisor as well as VM images. However, this makes PCI passthrough to the file server impossible. Another option is using the two 2.5" bays. In terms of reliability how are SSDs compared to e.g. WD RE4 disks? Would it make sense to have two SSDs in software RAID as boot disks for the hypervisor or should I just go with e.g. WD RE4 disks in a software RAID setup. I also need to think about where to store the mails for the mail server, but this could be done over NFS between the VMs. BTW, this is for home use, so the load is not really that big. What I'm looking for is best practices for splitting up a server.

  • Disk wipe preferences

    - by hmvm123
    I manage a pool of systems that are loaded with software and sent to potential customers for evaluations which often land sensitive information on the drives. Before shipping them back, they typically like a standard wipe to be run to clean out the drives. Most are familiar with DBAN so I try to make sure it can work on my systems. Unfortunately, this means I'm usually in RAID driver hell trying to make sure that the versions out there support the ones my systems are shipping with. These are various kinds of 3ware and LSI ones. Consequently, I have DBAN 1.0.7 working on some, a beta version of 2.0 on the others and 2.2.6 on some of the latest SSD based ones. Now with the LSI controllers on my IBM x3550 M3s (1064/1068) I'm getting no love at all. Is there a way out? Do you buildroot with DBAN and try to piece the drivers together? Any other tools, free or commerical, that stay updated. I'm trying to walk people of varying technical proficiencies through this, so a boot disk with simple choices is preferable.

  • Raid-z unaccessible after putting one disk offline

    - by varesa
    I have installed FreeNAS on a test server, with 3x 1Tb drives. They are setup in raidz. I tried to offline one of the disks (from the FreeNAS web-ui), and the array became degraded, as I think it should. The problem is with the array becoming unaccessible after that. I thought a raid like that should be able to run fine with one of the disks missing. Atleast very soon after I offline'd and pulled out the disk, the iSCSI share disappeared from a ESXi host's datastores. I also ssh'd into the FreeNAS server, and tried just executing ls /mnt/raid (/mnt/raid/ being the mount point). The whole terminal froze, not accepting ^C or anything. # zpool status -v pool: raid state: DEGRADED status: One or more devices are faulted in response to IO failures. action: Make sure the affected devices are connected, then run 'zpool clear'. see: http://www.sun.com/msg/ZFS-8000-HC scrub: none requested config: NAME STATE READ WRITE CKSUM raid DEGRADED 1 30 0 raidz1 DEGRADED 4 56 0 gptid/c8c9e44c-08e1-11e2-9ba6-001b212a83ea ONLINE 3 60 0 gptid/c96f32d5-08e1-11e2-9ba6-001b212a83ea ONLINE 3 63 0 gptid/ca208205-08e1-11e2-9ba6-001b212a83ea OFFLINE 0 0 0 errors: Permanent errors have been detected in the following files: /mnt/raid/ raid/iscsivol:<0x0> raid/iscsivol:<0x1> Have I understood the workings of a raidz wrong, or is there something else going on?

  • hp DL380 G4 won't boot with disk plugged into front USB

    - by Kev
    We outgrew a few older external USB backup drives, and purchased WD My Passport 1 TB USB 3.0 drives to replace them. When they are plugged into the front of our G4, it will blink forever after the BIOS (which is current, BTW) and never boot, even though the USB disks are not "bootable" per se. Our old drives did not exhibit this behaviour (so I don't think it's this type of issue that I've read about other servers.) The old drives were USB 2.0, but this shouldn't make a difference, AFAICT--the specs say all of the G4's USB ports are the same, 2.0, anyway, so I'm not sure how one port would handle a USB 3.0 device better than another. If we plug the new drives in one of the back slots, it boots fine. What's the cause? My concern is that the front USB port, and possibly the motherboard, might be starting to die. (We are experiencing other strange issues with them, or were initially, like intermittent file permissions errors despite wide-open ACL on these local drives, but some serverfault users have me convinced they may be coincidental software/security related issues.)

  • Hardware freeze during disk activity

    - by Thomi
    I built myself a linux-based NAS. It has several drives of various sizes and ages in an LVM configuration, with 800GB or so of data. The data is served using a simple samba server. This was working flawlessly, but after physically moving it, it has developed a strange fault: Whenever I do something on the server to cause disk activity, the entire machine freezes hard. This has the effect of killing any open network connections to the box, and generally making it useless. If I leave the machine for a few minutes it seems to come right again, but obviously this isn't really a solution. There are no error or warning messages in syslog, or the kernel logs. If I power the machine on, and leave it, it runs for several days without locking up. After that time I stopped testing. It doesn't freeze instantly - obviously it doesn't freeze while booting, and I can normally log in via SSH and start poking around in a few log files for a couple of minutes before it dies. My question is: What diagnostic tests can I run to determine the casuse?

  • Timely automatic unexpected reboot on ubuntu desktop

    We have a remote linux server (ubuntu desktop). The system log indicates the system has been restarted on the timely fashion. Here is a part of the last output: ut pts/0 192.169.50.2-sta Sat Nov 24 22:17 still logged in reboot system boot 2.6.32-21-generi Sat Nov 24 22:04 - 22:17 (00:13) ut pts/0 server.local Sat Nov 24 21:36 - crash (00:27) reboot system boot 2.6.32-21-generi Sat Nov 24 15:55 - 22:17 (06:21) reboot system boot 2.6.32-21-generi Fri Nov 23 18:02 - 22:17 (1+04:14) reboot system boot 2.6.32-21-generi Fri Nov 23 10:39 - 22:17 (1+11:38) reboot system boot 2.6.32-21-generi Fri Nov 23 04:18 - 22:17 (1+17:59) reboot system boot 2.6.32-21-generi Fri Nov 23 03:57 - 22:17 (1+18:20) reboot system boot 2.6.32-21-generi Thu Nov 22 20:38 - 22:17 (2+01:38) reboot system boot 2.6.32-21-generi Thu Nov 22 11:13 - 22:17 (2+11:03) reboot system boot 2.6.32-21-generi Thu Nov 22 08:12 - 22:17 (2+14:05) reboot system boot 2.6.32-21-generi Wed Nov 21 11:16 - 22:17 (3+11:00) reboot system boot 2.6.32-21-generi Tue Nov 20 22:36 - 22:17 (3+23:41) reboot system boot 2.6.32-21-generi Tue Nov 20 14:12 - 22:17 (4+08:05) reboot system boot 2.6.32-21-generi Tue Nov 20 11:32 - 22:17 (4+10:44) reboot system boot 2.6.32-21-generi Tue Nov 20 01:52 - 22:17 (4+20:25) reboot system boot 2.6.32-21-generi Tue Nov 20 00:22 - 22:17 (4+21:55) reboot system boot 2.6.32-21-generi Mon Nov 19 17:27 - 22:17 (5+04:50) It looks the system is set to be restarted at 22:17.

  • Incredble low disk performance on HP DL385 G7

    - by 3molo
    Hi, As a test of the Opteron processor family, I bought a HP DL385 G7 6128 with HP Smart Array P410i Controller - no memory. The machine has 20GB ram 2x146GB 15k rpm SAS + 2x250GB SATA2, both in Raid 1 configurations. I run Vmware ESXi 4.1. Problem: Even with one virtual machine only, tried Linux 2.6/Windows server 2008/Windows 7, the VMs' feel really sluggish. With windows 7, the vmware converter installation even timed out. Tried both SATA and SAS disks and SATA disks are nearly unsusable, while SAS disks feels extremely slow.I can't see a lot of disk activity in the infrastructure client, but I haven't been looking for causes or even tried diagnostics because I have a feeling that it's either because of the cheap raid controller - or simply because of the lack of memory for it. Despite the problems, I continued and installed a virtual machine that serves a key function, so it's not easy to take it down and run diagnostics. Would very much like to know what you guys have to say of it, is it more likely to be a problem with the controller/disks or is it low performance because of budget components? Thanks in advance,

  • IBM BladeCenter S: Disk Configuration

    - by gravyface
    Have just the one storage bay right now (SAS 15K 600GB x 6) and have configured one storage pool in RAID 10 with 4 disks (and two global spares). For each blade, I've created a volume and mapped accordingly: Blade #1 400 GB Blade #2 200 GB Blade #3 100 GB Blade #4 100 GB When I boot up Blade 1 and enter into the UEFI Setup (F1) followed by the Adapters and UEFI Drivers LSI Logic Fusion MPT SAS Driver Utility, I see 4 disks: two are the on-board 73GB drives, the other two are 200GB each and assume I'm being presented with two logical disks from the volume I created and mapped to this blade. I was a bit surprised by this: I figured I would've been presented with one logical drive per volume, not two. I'm assuming I can just configure whatever RAID level I wish that supports two disks, but not really sure what the benefits/trade-offs here. Should I go with RAID 10 on top of RAID 10? RAID 0? Software RAID 0/1/10? Does it even matter? If this is "normal" to see two disks, then I'm going to likely just do some benchmarking and see if it makes a difference changing the RAID levels (my guess is no); if this is not normal, well, please let me know. :)

  • Discrepancy in file size on disk and ls output

    - by smokinguns
    I have a script that checks for gzipped file sizes greater than 1MB and outputs files along with their sizes as a report. This is the code: myReport=`ls -ltrh "$somePath" | egrep '\.gz$' | awk '{print $9,"=>",$5}'` # Count files that exceed 1MB oversizeFiles=`find "$somePath" -maxdepth 1 -size +1M -iname "*.gz" -print0 | xargs -0 ls -lh | wc -l` if [ $oversizeFiles -eq 0 ];then status="PASS" else status="CHECK FAILED. FOUND FILES GREATER THAN 1MB" fi echo -e $status"\n"$myReport The problem is that ls command outputs the files sizes as 1.0MB in the report but the status is "FAIL" as "$oversizeFiles" variable's value is 2. I checked the file sizes on disk and 2 files are 1.1MB. Why this discrepancy? How should I modify the script so that I can generate an accurate report? BTW, I'm on a Mac. Here is what man page for "find" says on my Mac OSX: -size n[ckMGTP] True if the file's size, rounded up, in 512-byte blocks is n. If n is followed by a c,then the primary is true if the file's size is n bytes (characters). Similarly if n is followed by a scale indicator then the file's size is compared to n scaled as: k kilobytes (1024 bytes) M megabytes (1024 kilobytes) G gigabytes (1024 megabytes) T terabytes (1024 gigabytes) P petabytes (1024 terabytes)

  • Hard Disk based storage library

    - by Ryan M.
    We have a Tandberg T24 tape device to handle all of our long term backups right now. We decided that we're not backing up nearly everything that we would like to and that we still have a lot of vulnerabilities. To get to where we want to be, we're going to have to back up a lot more servers than we're currently doing. All of our internal servers have some sort of directly attached drive (I.e. LaCie Raid box or a simple portable hard drive) doing backups, but what we want to do is get those backups off-site. The current tape drive is directly attached via SCSI to a Windows Server 2008 File Server. So to back up anything to tape, it has to be funneled through the File Server. With the current increase that we have planned, I don't think that funneling everything through the File Server is the right course of action and I'm thinking that maybe a second backup device would be more appropriate. I would like your input on a couple of ideas. 1) Doing HDD instead of tape. Tape is hard to deal with. We have a regular rotation cycle, so they don't need years and years of shelf life, so I'm wondering if something HDD-based would be better. 2) Something accessible over the network. Instead of having the device directly attached to one specific machine, have it available to all the servers over the network. Our File Server is a 12-disk raid 6 set up.. I was thinking something like that, but with no raid involved, all disks are stand alone so they can be used/installed/removed on an individual basis. Does any such thing exist? Thanks for your ideas. I'm really interested to hear about some of the solutions you guys are using..

  • Bacula stops writing to disk volume after 2GB

    - by m.list
    Bacula Version: 5.2.5 I have configured bacula to write volumes to disk, however bacula stops writing to the volume as soon as it reaches 2gb. The file system is not an issue as I have stored files larger than 2gb. 06-Dec 17:22 backup-sd JobId 8421: End of Volume "Full-Monthly-0005" at 0:2147475577 on device "FileStorage" (/nfs/backup-pool). Write of 64512 bytes got 8069. 06-Dec 17:22 backup-sd JobId 8421: End of medium on Volume "Full-Monthly-0005" Bytes=2,147,475,578 Blocks=33,288 at 06-Dec-2012 17:22. backup1@backup:/nfs/backup-pool$ ls -alh Full-Monthly-0005 <br> -rw-r----- 1 bacula tape 2.0G Dec 3 16:14 Full-Monthly-0005 bacula-dir.conf: Pool { Name = Full-Monthly Pool Type = Backup Recycle = yes Volume Retention = 5 months Volume Use Duration = 1 day Maximum Volumes = 5 Maximum Volume Bytes = 12gb } bacula-sd.conf: Device { Name = FileStorage Media Type = File Archive Device = /nfs/backup-pool LabelMedia = yes # lets Bacula label unlabeled media Random Access = Yes RemovableMedia = no AlwaysOpen = no Label media = yes Maximum Volume Size = 12gb } In my original configuration Maximum Volume Bytes and Maximum Volume Size were not set at all and so should have defauted to no maximum but that did not work either.

  • can't save or create files in external hard disk

    - by Rodniko
    i formatted my computer and installed new win7. i connected my external hard disk (usb connector) and i have some kind of permission problem. i can't save files after opening them and right clicking and choosing "new" shows that i can only create folders. what is wrong ? why doesn't the external hd doesn't have permission and how do i cahnge it? in microsoft they probably thought: "hmmm.... how would i make it difficult for the user to use our product..." , "we will have to make the difficulty as soon as the windows is installed...." " but how would we guarantee 100% for the user to have problems? "oh yhe! block creating files and saving them, yes!" i'm so tired of those guys... my HD is half a Terra, changing ownership of all the files inside will take a couple of hours , i need other ideas... if any...
