  • Access NFS share from cygwin?

    - by Jason Voegele
    We have a Windows 2003 Server on which we have installed Microsoft's Services for UNIX, and we have mounted a few NFS shares that contain shared resources that we need to access from this box. When I log in to this server with remote desktop, I am able to browse the contents of the NFS shares and everything works fine. However, one use case that we have is that we need to access this server using SSH, and still be able to access the NFS shares. We are running the Cygwin SSH daemon to provide SSH access to the server, but for some reason when we log in to the Windows 2003 server using SSH we can no longer access the NFS shares. To demonstrate, here is the output of the 'mount' command, first from a Cygwin shell when logged in with remote desktop: $ mount C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) O: on /cygdrive/o type nfs (binary,posix=0,user,noumount,auto) P: on /cygdrive/p type nfs (binary,posix=0,user,noumount,auto) Z: on /cygdrive/z type nfs (binary,posix=0,user,noumount,auto) And now, the same 'mount' command when logged in with SSH: $ mount C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) Notice the missing O: P: and Z: NFS shares in the latter. Can anyone tell me why I am unable to see these NFS shares when logged in with SSH? Thanks!

  • Poor write performance on Debian server running NFS with 22TB exported JFS filesystem

    - by user143546
    I am currently running a debian server that is exporting a large JFS filesystem (22TB) over NFS (nfs-kernel-server.) When attempting to write to the NFS share, the performance is very poor. The 22TB disk is sitting on a NAS mounted using iSCSI. It will bust for a moment near expected line speed, and then sit idle for several seconds. Very little traffic measured in the low kb/sec. The wait peeks on write. When reading from the NFS mount, the system operates at expected speeds (11MB/sec). The issue does not occur when using SFTP, rsync, or local coping (non-nfs). The issue persists between stable and testing releases. On the same machine I have a 14TB ext4 filesystem using the exact same export configuration that does not share the issue. This share is not in regular use and thus not consuming resources. NFS Server: cat /etc/exports /data2 10.1.20.86(rw,no_subtree_check,async,all_squash) cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /etc/default/nfs-kernel-server RPCNFSDCOUNT=8 RPCNFSDPRIORITY=0 RPCMOUNTDOPTS=--manage-gids NEED_SVCGSSD= RPCSVCGSSDOPTS= NFS Client: cat /etc/fstab 10.1.20.100:/data2 /root/incoming nfs rw,noatime,soft,intr,noacl 0 2 cat /sys/block/sdb/queue/scheduler noop [deadline] cfq cat /proc/mounts 10.1.20.100:/data2/ /root/incoming nfs4 rw,noatime,vers=4,rsize=262144,wsize=262144,namlen=255,soft,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.1.20.86,minorversion=0,addr=10.1.20.100 0 0 This problem has me pretty stumped. Any help would be greatly welcomed. Thanks.

  • Mounted NFS directory not writable by Apache / PHP

    - by phpfour
    Need some help here with NFS. Here's what I have (all servers running CentOS 5.6 with SELinux): 172.17.20.1 - Primary server with static IP. Varnish redirects requests to the web servers. 172.17.20.2 - Web server 1 172.17.20.3 - Web server 2 The application residing on the web servers is running Drupal and I need both of them to share the same files directory. I have created a folder in 172.17.20.1 called /var/nfs with root user. Here is my /etc/exports content: /var/nfs 172.17.20.2(rw,sync,no_root_squash) 172.17.20.3(rw,sync,no_root_squash) On both the web servers (172.17.20.2/3), I have it mounted like below: [root@web2 ~]# mount ... 172.17.20.1:/var/nfs on /mnt/nfs/var/nfs type nfs (rw,sync,hard,intr,addr=172.17.20.1) On all the servers, I've added the user apache to the root group to get the desired write access: [root@main ~]# cat /etc/group root:x:0:root,apache .... .... apache:x:48: [root@web1 ~]# cat /etc/group root:x:0:root,apache .... .... apache:x:48: Despite all this, when I try to write files into the /mnt/nfs/var/nfs folder from Drupal/PHP, it cannot write to it. I even tried with a simple PHP upload script but it doesn't work, so the problem is not with Drupal. Any help you guys can do is much appreciated. I've spent hours and hours with it, without any success :( Thanks in advance.

  • Trying to mount an NFS directory from a Mac with another user

    - by Yair
    I have a username on an ubuntu server, lets call it user a. I want to mount a directory from that server to my Mac, on which I have another username, lets call it user b. My problem is that, after I mount the directory (using the disk utility app) I can view files on the server but can't modify or create new files on it. I checked, and if I change the permissions of the server directory so that its open to everyone (chmod 777), I can write to it. So what I need to know, is how can I specify the username and password in the NFS client when setting up the mount? That is, I want to specify that I'm trying to log in as user a to the server.

  • NFS host is not exporting the "share"

    - by user1345260
    I have a NFS Server: usanfsd01 And a remote machine: usafssd01 I tried mounting a directory from usafssd01 onto usanfsd01 by adding the following line to /etc/fstab as root usanfsdo1:/home/dblogs /home/data/dblogs nfs rw 0 0 And when I run the following command to see if NFS is exporting the share, it's not shown showmount -e usanfsdo1 Can someone please help? Also, a point of interest would be there is another mount that works on the same servers and thats defined as below in the /etc/fstab usanfsdo1:/home/files /home/data/files nfs rw 0 0 /etc/exports /nfs/home/dblogs 'IPADDRESS'(rw,no_root_squash)

  • How to use Client for NFS on Windows Vista?

    - by netvope
    I've installed "Client for NFS" on my 32-bit Windows Vista Ultimate. However, I can't find it in the start menu, and can't find any documentation on how to use it. How do I connect to a NFS share using "Client for NFS"? Can I map it to a drive letter? How do I choose connection options, such as my uid/gid, mount as read-only, port number, etc? Ideally I would like to map a NFS share using the command line. You may also suggest alternatives to "Client for NFS".

  • "Network Error - 53" while trying to mount NFS share in Windows Server 2008 client

    - by Mike B
    CentOS | Windows 2008 I've got a CentOS 5.5 server running nfsd. On the Windows side, I'm running Windows Server 2008 R2 Enterprise. I have the "Files Services" server role enabled and both Client for NFS and Server for NFS are on. I'm able to successfully connect/mount to the CentOS NFS share from other linux systems but am experiencing errors connecting to it from Windows. When I try to connect, I get the following: C:\Users\fooadmin>mount -o anon 10.10.10.10:/share/ z: Network Error - 53 Type 'NET HELPMSG 53' for more information. (IP and share name have been changed to protect the innocent :-) ) Additional information: I've verified low-level network connectivity between the Windows client and the NFS server with telnet (to the NFS on TCP/2049) so I know the port is open. I've further confirmed that inbound and outbound firewall ports are present and enabled. I came across a Microsoft tech note that suggested changing the "Provider Order" so "NFS Network" is above other items like Microsoft Windows Network. I changed this and restarted the NFS client - no luck. I've confirmed that the share folder on the NFS server is readable/writable by all (777) I've tried other variations of the mount command like: mount 10.10.10.10:/share/ z: and mount 10.10.10.10:/share z: and mount -o anon mtype=hard \\10.10.10.10:/share * No luck. As per the command output, I tried typing NET HELPMSG 53 but that doesn't tell me much. Just "The network path was not found". I'm lost on how to proceed with troubleshooting. Any ideas?

  • apt-get doesnt download files from NFS location

    - by Pravesh
    I have switched to unix from last 3 months and trying to understand install process and in particular apt-get. I am able to successfully install and download the packages when I configure my repository on http location in /etc/apt/sources.list file. e.g. deb http://web.myspqce.com/u/eng/rose/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free This command will download(/var/cache/apt/archive) and install the package when i use apt-get install When I change the source location to file instead of http(nfs mount point), the package is getting installed but NOT getting downloaded in /var/cache/apt/archive. deb file:/deb_repository/debian-mirror-squeeze-amd64/mirror/ftp.us.debian.org/debian/ squeeze main contrib non-free Please let me know if there is any configuration or settings that i have to make to let apt-get to both download and install package when i use (nfs)file:/ instead of http:/ in sources.list. To achieve this, I can use apt-get --downlaod-only and then use apt-get install for both download and install in two separate calls, but I want to know why package is not getting downloaded with apt-get install but only getting installed when used with file:/ in sources.list

  • How to make NFS mounts available while offline?

    - by lpanebr
    Problem: I work on a notebook and while at work I have access to many NFS mounted drives. When I get home they are obviously not available. Windows 7 solution: My business partner uses Windows 7 and maps the folders via samba. Windows 7 has a very nice feature that let's he make these folders available offline. So when when he connects to the work network the changes get synchronized! Question: Is there a way to mimic that in ubuntu? What I have now: Server to local sync: I have added rsync entries on my crontab to copy server folders => local folders every five minutes. When at work I used the NFS mapped folders and while outside work I use the local copies. When I get at work I manually run a script that syncs local folders => server folders. Problems with my setup: slow startup when not at work (I guess do to the fstab trying to map the server folders) no conflict checking/managing I have to remember to sync manually and be careful because of the different file locations recent files do not work between work and home

  • NFS caching on Ubuntu

    - by stream
    We run a bunch of ubuntu servers (mostly 8.04 LTS) which all mount an nfs share at /nfs. We use the nfs primarily for two purposes: symlinking config files (such as apache vhosts) reading & writing uploaded files This all works great except it makes us fully dependent on the central NFS server (which is a DRBD cluster with heartbeat failover from primary to secondary, but we've still seen issues). What we'd like is if we could mount the NFS through some local caching layer which would make any file which had previously been read remain available even if /nfs isn't. Writes could be disabled for this period. Searching around it looks like cachefilesd may be an option. Unfortunately, it's only packaged for ubuntu 9.10 & 10.04 it looks like. I was also looking for a FUSE-based solution which might fit the bill, but hadn't found anything yet. Any suggestions would be greatly appreciated!

  • Mac OS X & Linux: mount_nfs: can't access /nfs: Permission denied

    - by MountainX
    I have an Ubuntu 12.04 NFS server and I have an iMac NFS client running OS X 10.6.8. I believe I have everything set up properly, yet I still get this error on the Mac: mount_nfs: can't access /nfs: Permission denied My exports on the Linux server uses the insecure option like this: /export/home/me/ 192.168.100.132(rw,subtree_check,insecure,nohide) Where 192.168.100.132 is the address of my Mac. I have even tried using -o resvport on the Mac (in addition to insecure on Linux) and I still get the same error as above. $ sudo mount -t nfs -o resvport 192.168.100.1:/home/me /Users/me/mount Here is the output of showmount: # showmount -e 192.168.100.1 Export list for 192.168.100.1: /export/home/me 192.168.100.132 .... I have reviewed this similar question: How to mount NFS export on Mac OS X?

  • How do I set up a Windows NFS share so that I can view it's contents on Linux?

    - by hewhocutsdown
    My NFS server is a Windows XP SP3 box with the Microsoft Windows Services for Unix installed. I have a share configured under C:\NFS with the share name NFS and ANSI encoding. Anonymous access is enabled, with the anon UID/GID set to 0/0. Additionally, I've set ALL MACHINES to Read-Write, and checked the checkbox to Allow root access. My first NFS client is a Ubuntu 10.04 box, with nfs-common installed. Running sudo mount -t nfs 1.1.1.1:/NFS /home/user/NFS succeeds, but when I attempt to view the folder (even as root), it tells me that I do not have the permissions necessary to view the contents of the folder. My second NFS client is an IBM iSeries box running OS/400 V5R3. I used the mount command below: MOUNT TYPE(*NFS) MFS('1.1.1.1:/NFS') MNTOVRDIR('/PARENT/NFS') OPTIONS('rw,nosuid,retry=5,rsize=8096,wsize=8096,timeo=20,retrans=2,acregmin=30,acregmax=60,acdirmin=30,acdirmax=60,soft') CODEPAGE(*BINARY *ASCII) which also mounts successfully. Attempting to WRKLNK '/PARENT/NFS' and use Option 5 to enter the directory yields a Not authorized to object error - even though I am a security officer with the *ALLOBJ special authority. My gut says that it's a problem with the Windows share, but I don't know what it could be. Do you have any suggestions?

The dragonflyBSD exports file like this: /tank -mapall=root windows-client and i setup my windows 2008 a NFS client all right. There is my win cmd to mount NFS. mount \\dragonfly-server\tank e:\ After finished my configuration. I found the windows client can mount the remote tank partition. And i can create a file or a dir. But when i try to delete the file i just create. It alerts permission deny. You must have the permission.And the same result when i try to write to the text i create in the NFS partition I don't know why i just can create the file through NFS, but can't do any thing else. Is there any body can help?

  • How can I remount an NFS volume on Red Hat Linux?

    - by user76177
    I changed the user id of a user on an NFS client that mounts a volume from another server. My goal is to get the 2 users to have the same id, so that both servers can read and write to the volume. I changed the id successfully on the client system, but now when I look at the NFS mount from that system, it reports the files being owned by the old id. So it looks like I need to "refresh" that mount. I have found many instructions on how to remount, but each seems slightly different according to the type of system. Is there a simple command I can run to get the mounted volume to refresh so that it interprets the new user settings?

  • Which to use NFS or Samba?

    I am setting up a box to be a file server at the house. It will mainly be used to share music, pictures, movies with other linux boxes on the network, and one OS X machine. From what I have read NFS and samba would work in my situation, and as such I am not sure which to choose. What is important to me is the speed transfers between boxes and how difficult it is to setup. Which would you recommend and why?

  • NFS issue brings down entire vSphere ESX estate

    - by growse
    I experienced an odd issue this morning where an NFS issue appeared to have taken down the majority of my VMs hosted on a small vSphere 5.0 estate. The infrastructure itself is 4x IBM HS21 blades running around 20 VMs. The storage is provided by a single HP X1600 array with attached D2700 chassis running Solaris 11. There's a couple of storage pools on this which are exposed over NFS for the storage of the VM files, and some iSCSI LUNs for things like MSCS shared disks. Normally, this is pretty stable, but I appreciate the lack of resiliancy in having a single X1600 doing all the storage. This morning, in the logs of each ESX host, at around 0521 GMT I saw a lot of entries like this: 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4cf9a8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4dc9e8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4d3fa8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4de0a8 3 [....] 2011-11-30T06:16:07.042Z cpu0:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:17:01.459Z cpu2:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:25:17.887Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000a4c2b28 3 2011-11-30T06:27:16.063Z cpu3:4011)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:35:30.827Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:36:37.953Z cpu6:2054)NFS: 292: Restored connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:40:08.242Z cpu6:2054)NFSLock: 608: Stop accessing fd 0x41000a4c3e68 3 2011-11-30T06:40:34.647Z cpu3:2051)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:44:42.663Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:44:53.973Z cpu0:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:51:28.296Z cpu5:2058)NFSLock: 608: Stop accessing fd 0x41000ae3c528 3 2011-11-30T06:51:44.024Z cpu4:2052)NFSLock: 568: Start accessing fd 0x41000ae3b8e8 again 2011-11-30T06:56:30.758Z cpu4:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:56:53.389Z cpu7:2055)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T07:01:50.350Z cpu6:2054)ScsiDeviceIO: 2316: Cmd(0x41240072bc80) 0x12, CmdSN 0x9803 to dev "naa.600508e000000000505c16815a36c50d" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x24 0x0. 2011-11-30T07:03:48.449Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000ae46b68 3 2011-11-30T07:03:57.318Z cpu4:4009)NFSLock: 568: Start accessing fd 0x41000ae48228 again (I've put a complete dump from one of the hosts on pastebin: http://pastebin.com/Vn60wgTt) When I got in the office at 9am, I saw various failures and alarms and troubleshooted the issue. It turned out that pretty much all of the VMs were inaccessible, and that the ESX hosts either were describing each VM as 'powered off', 'powered on', or 'unavailable'. The VMs described as 'powered on' where not in any way reachable or responding to pings, so this may be lies. There's absolutely no indication on the X1600 that anything was awry, and nothing on the switches to indicate any loss of connectivity. I only managed to resolve the issue by rebooting the ESX hosts in turn. I have a number of questions: What the hell happened? If this was a temporary NFS failure, why did it put the ESX hosts into a state from which a reboot was the only recovery? In the future, when the NFS server goes a little off-piste, what would be the best approach to add some resilience? I've been looking at budgeting for next year and potentially have budget to purchase another X1600/D2700/disks, would an identical mirrored disk setup help to mitigate these sorts of failures automatically? Edit (Added requested details) To expand with some details as requested: The X1600 has 12x 1TB disks lumped together in mirrored pairs as tank, and the D2700 (connected with a mini SAS cable) has 12x 300GB 10k SAS disks lumped together in mirrored pairs as sastank zpool status pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0s0 ONLINE 0 0 0 errors: No known data errors pool: sastank state: ONLINE scan: scrub repaired 0 in 74h21m with 0 errors on Wed Nov 30 02:51:58 2011 config: NAME STATE READ WRITE CKSUM sastank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t14d0 ONLINE 0 0 0 c7t15d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t16d0 ONLINE 0 0 0 c7t17d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t18d0 ONLINE 0 0 0 c7t19d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t20d0 ONLINE 0 0 0 c7t21d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t22d0 ONLINE 0 0 0 c7t23d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t24d0 ONLINE 0 0 0 c7t25d0 ONLINE 0 0 0 errors: No known data errors pool: tank state: ONLINE scan: scrub repaired 0 in 17h28m with 0 errors on Mon Nov 28 17:58:19 2011 config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t5d0 ONLINE 0 0 0 c7t6d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t8d0 ONLINE 0 0 0 c7t9d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t10d0 ONLINE 0 0 0 c7t11d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t12d0 ONLINE 0 0 0 c7t13d0 ONLINE 0 0 0 errors: No known data errors The filesystem exposed over NFS for the primary datastore is sastank/VMStorage zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 45.1G 13.4G 92.5K /rpool rpool/ROOT 2.28G 13.4G 31K legacy rpool/ROOT/solaris 2.28G 13.4G 2.19G / rpool/dump 15.0G 13.4G 15.0G - rpool/export 11.9G 13.4G 32K /export rpool/export/home 11.9G 13.4G 32K /export/home rpool/export/home/andrew 11.9G 13.4G 11.9G /export/home/andrew rpool/swap 15.9G 29.2G 123M - sastank 1.08T 536G 33K /sastank sastank/VMStorage 1.01T 536G 1.01T /sastank/VMStorage sastank/comstar 71.7G 536G 31K /sastank/comstar sastank/comstar/sql_tempdb 6.31G 536G 6.31G - sastank/comstar/sql_tx_data 65.4G 536G 65.4G - tank 4.79T 578G 42K /tank tank/FTP 269G 578G 269G /tank/FTP tank/ISO 28.8G 578G 25.9G /tank/ISO tank/backupstage 2.64T 578G 2.49T /tank/backupstage tank/cifs 301G 578G 297G /tank/cifs tank/comstar 1.54T 578G 31K /tank/comstar tank/comstar/msdtc 1.07G 579G 32.8M - tank/comstar/quorum 577M 578G 47.9M - tank/comstar/sqldata 1.54T 886G 304G - tank/comstar/vsphere_lun 2.09G 580G 22.2M - tank/mcs-asset-repository 7.01M 578G 6.99M /tank/mcs-asset-repository tank/mscs-quorum 55K 578G 36K /tank/mscs-quorum tank/sccm 16.1G 578G 12.8G /tank/sccm As for the networking, all connections between the X1600, the Blades and the switch are either LACP or Etherchannel bonded 2x 1Gbit links.

  • NFS Datastore Appears Empty!

    - by daemonchild
    Hi guys, I've got an NFS server problem. The datastore connected and seems to be a valid datastore in both the vSphere client and under /vmfs/volumes. The issue is that it appears to be empty! I can create files (eg: touch /vmfs/volumes/nfs_common/thefile) and it is correctly written to the nfs store. I can verify this by looking on the nfs server itself. But the vmkernel only sees an empty datastore; the file disappears. Another freebsd box can mount the same NFS share and see the files correctly. Some useful data: ESXi 4.0.0 Build 208167 NFS is unfsd running on a Buffalo Linkstation Pro Duo (a bit hacky I know). The share has file system permissions set to 777 at the moment. My /etc/exports is as follows, and as I say it connects fine. /mnt/array1/ESX_Shared 192.168.16.0/255.255.255.0(insecure,rw,sync,no_root_squash,no_subtree_check) The ESXi servers can also successfully mount NFS shares from other NFS servers. Any ideas guys? Thanks, Tom

  • NFS on top of GFS2 - does it work?

    - by Matthew
    We're currently using a NoSQL derivative called Splunk to receive our data. The software supports something called "search head pooling" in which the job-dispatching engine is housed on several servers which share a common storage point. Originally our intention was to use a clustered filesystem like GFS2 because of low latency, stability, and ease of setup. We set up GFS2, and it's working with no issues. However when trying to run the software, it's trying to create lock files, and a bunch of other things that their support team can't quite explain. Ultimate feedback from them was that they only support NFS. Our network administration team heavily frowns on NFS (lack of stability, file lock issues, etc). So, I was thinking about the possibility of setting up NFS on each server in the cluster to act as a wedge layer between the GFS2 filesystem and the software. Basically configure each server to export the GFS2 filesystem's mountpoint via NFS, and then tell each server to connect to that NFS share. That way we aren't introducing any single-points-of-failure should a dedicated NFS server go down, but the vendor gets their "required" NFS share. I'm just brainstorming ways around, so please tear this apart :)

  • NFS server hangs after 3 minutes

    - by John P
    I have a VPS running Centos 6.3 with a fully updated NFS. When I mount the NFS directory from the client, everything works perfectly fine for approximately 3 minutes, then the client hangs attempting to see the directory. nfs-utils-1.2.3-26.el6.x86_64 service nfs status rpc.svcgssd is stopped rpc.mountd (pid 2544) is running... nfsd (pid 2609 2608 2607 2606 2605 2604 2603 2602) is running... rpc.rquotad (pid 2540) is running... cat /etc/exports /home/user XX.XX.XX.20(rw,async,no_root_squash) The client is running Centos 5.8. The directory is mounted using mount x.x.x.6:/home/user /mnt When everything is working, I get the following on the client: /usr/sbin/rpcinfo -p X.X.X.6 | grep mountd 100005 1 udp 892 mountd 100005 1 tcp 892 mountd 100005 2 udp 892 mountd 100005 2 tcp 892 mountd 100005 3 udp 892 mountd 100005 3 tcp 892 mountd When it stops working, rpcinfo just hangs on the client, however running the above command on the server does return data. There are no logs on the NFS Server side that would indicate an issue. On the client side, I see: cat /var/log/messages kernel: nfs: server X.X.X.6 not responding, still trying The client and server are plugged into the same switch, however they are on different networks. The server is a VPS while the client is a dedicated box. SELINUX is in permissive mode on both client and server, and I've turned iptables off on the server to make sure that was not causing an issue. Any ideas would be helpful - right now I'm having to restart NFS every two minutes in a cron job to keep it semi working. Thanks

  • Mounting NFS directory causes creating Zero byte files

    - by Alaa
    I have two Servers, Server X (IP 192.168.1.1) and Server Y (IP 192.168.1.2), both of them are ubuntu 9.1 i have created varnish load balancer on them for my drupal website (pressflow 6.22) I have mounted a directory of imagecache from server X to Y as below @X:/etc/exports == /var/www/proj/htdocs/sites/default/files/images 192.168.1.2(rw,async,no_subtree_check) @Y:/etc/fstab == 192.168.1.1:/var/www/proj/htdocs/sites/default/files/images var/www/proj/htdocs/sites/default/files/images nfs defaults 0 0 also i made this on server X X:/var/www/proj/htdocs/sites/default/files$ chmod -R 777 images i tried to touch, rm, vim, and cat files in images directory that has been mounted on Y and everything went fine. now, ALWAYS when server Y's imagecache tries to create an image in images directory, the image is created with ZERO byte file size. anyone face the same before? any idea of how to fix this problem or what might cause it? Thanks for your help
