  • saslauthd using too much memory

    - by Brian Armstrong
    Woke up today to see my site slow/unresponsive. Pulled up top and it looks like a ton of saslauthd processes have spun up using about 64m of RAM each, causing the machine to enter swap space. I've never seen this many used on there. top - 16:54:13 up 85 days, 11:48, 1 user, load average: 0.32, 0.50, 0.38 Tasks: 143 total, 1 running, 142 sleeping, 0 stopped, 0 zombie Cpu(s): 0.7%us, 0.3%sy, 0.0%ni, 97.3%id, 0.2%wa, 0.0%hi, 0.0%si, 1.4%st Mem: 1048796k total, 1025904k used, 22892k free, 14032k buffers Swap: 2097144k total, 332460k used, 1764684k free, 194348k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 848 admin 20 0 263m 115m 4840 S 0 11.3 5:02.91 ruby 906 admin 20 0 265m 113m 4828 S 0 11.1 5:37.24 ruby 30484 admin 20 0 248m 91m 4256 S 6 9.0 219:02.30 delayed_job 4075 root 20 0 160m 65m 952 S 0 6.4 0:24.22 saslauthd 4080 root 20 0 162m 64m 936 S 0 6.3 0:24.48 saslauthd 4079 root 20 0 162m 64m 936 S 0 6.3 0:24.70 saslauthd 4078 root 20 0 164m 63m 936 S 0 6.2 0:24.66 saslauthd 4077 root 20 0 163m 62m 936 S 0 6.1 0:24.66 saslauthd 3718 mysql 20 0 312m 52m 3588 S 1 5.1 3499:40 mysqld 699 root 20 0 72744 7640 2164 S 0 0.7 0:00.50 ruby 15701 postfix 20 0 106m 5712 4164 S 1 0.5 0:00.50 smtpd 15702 postfix 20 0 52444 3252 2452 S 1 0.3 0:00.06 cleanup 4062 postfix 20 0 41884 3104 1788 S 0 0.3 125:26.01 qmgr 15683 root 20 0 51504 2780 2180 S 0 0.3 0:00.04 sshd 14595 postfix 20 0 52308 2548 2304 S 1 0.2 0:24.60 proxymap 15483 postfix 20 0 43380 2544 1992 S 0 0.2 0:00.38 smtp 15486 postfix 20 0 43380 2544 1992 S 0 0.2 0:00.36 smtp 15488 postfix 20 0 43380 2540 1992 S 0 0.2 0:00.38 smtp 15485 postfix 20 0 43380 2532 1984 S 0 0.2 0:00.36 smtp 15489 postfix 20 0 43380 2532 1984 S 0 0.2 0:00.40 smtp Wasn't sure what Saslauthd is, Google says it handles plantext authentication. The machine has been sending a lot of email through postfix, so this could be related. Anyone know why so many may have spun up? Are they safe to kill? Thanks!

  • Sharing two SSL wildcard certificates in memory in nginx

    - by hvtilborg
    I have an nginx server running with two IP addresses, say 1.2.3.4 and 4.3.2.1. Besides there are two wildcard SSL certificates for *.example.net (i.e. wc1, pointing to 1.2.3.4) and *.sub.example.net (i.e. wc2, pointing to 4.3.2.1). The nginx docs mention that you can share a wildcard certificate between server instances like this: ssl_certificate wc1.crt; ssl_certificate_key wc1.key; server { listen 1.2.3.4:443; server_name www.example.net; ssl on; ... } server { listen 1.2.3.4:443; server_name test.example.net; ssl on; ... } However, I was wondering whether this same construct is possible to use with the second wildcard certificate too. Both domains have around 500 subdomains. Do they not get mixed up, since the ssl_certificate construct is now global?

  • What is consuming memory?

    - by Milan Babuškov
    Feel free to change the question title. I have a VPS with standard LAMP stack and a busy website. Operating system is CentOS 5.5. Virtualization is done with VMWare. My server gets real slow about every 6 hours. Logging into it I see that 1.6GB of RAM is consumed. However, listing the active processes does not explain the problem. Can anyone make any sense of this? "free" shows this: total used free shared buffers cached Mem: 2059456 2049280 10176 0 14780 380968 -/+ buffers/cache: 1653532 405924 Swap: 2096472 96 2096376 While this is output of "ps": [root@vmi29 /]# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 10348 688 ?

  • How do I get a Wireless N PCi card to connect to a wireless G router?

    - by Andy
    I'm having some problems setting up a new wireless PCI card on a WinXP SP3 PC. I know that the router is configured correctly. It is a Linksys WRT54GL, using 802.11b/g. Security mode is WPA2 Personal with TKIP+AES encryption. I am able to connect to this fine using my laptop (first gen MacBook with a 802.11b built in card). The new PCI card is also Linksys, but it supports 802.11n. Card seems to be installed ok (Windows sees it fine, doesn't list any errors in Device Manager), however when it scans for available wireless networks it can't find my wireless network (the router is set to broadcast the SSID). I tried to enter the network SSID manually, but that didn't seem to help. I chose WPA2-PSK for network authentication. The only options for encryption are TKIP or AES - I've tried both, neither worked. I am sure that I typed in my wireless key correctly. At this point, I don't think the problem is with encryption, but something else. It almost seems like I need to switch the wireless card into g mode, but I haven't found a way to do that (if that is even possible/necessary - I thought n was fully backwards compatible with g). Also, the PC is in the same room as the router, and my laptop, so I don't think that it is an interference issue. Any ideas what I'm doing wrong? I'm running out of things to try at this point. :(

  • question about that concept of linux install in flash card.

    - by Johnny
    1.i can't understand why Linux on flash card need install, does it simply copy certain file to certain location in flash card? ---i mean ,plan it in a response file,then one program read the plan in response file and write certain format to flash card. 2.does the file system bind tightly to the linux kernel? is it possible let each kernel,user,app have its own root? rather than mount everything under one single / "root"

  • I disconnected my cellphone while transferring files to its Mini SD card. Now the files aren't there

    - by Martín Fixman
    I use Ubuntu 9.10, and the MiniSD card shows as having the space used as if there were files. Baobab (the disk usage analyzer) shows that the card only has 118 MB used (of the 401 Ubuntu claims there are). Of course, I already tried the obvious (rebooting the phone, adding and removing files, etc.), but I don't want to format my card, because I still have some files on it, the transfer to my computer is slow, and because I use an old wire it fails often.

  • How to confirm memcache memory increase?

    - by Peter Johansson
    Alright, I have downloaded /etc/sysconfig/memcache And edited the file that contained "PORT="11211" USER="memcached" MAXCONN="1024" CACHESIZE="64" OPTIONS="" to 1000 cachesize. I uploaded the file back to the server. Now I know there is a way to check if the changes took effect, but I cant remember how. I tried "memcached-tool 127.0.0.1:11211 stats" but it didnt show me the RAM size. Any help would be appreciated.

  • Ubuntu won't boot from USB memory stick

    I used the instructions on this webpage to create a bootable USB drive for running Ubuntu 9.10. Unfortunately it doesn't work on my EeePC.

  • Radeon 4670 Card Has 2 DVI Outs But Only Works When One is used in Win7 x64

    - by ssmith
    I have an ATI XFX Radeon 4670 1GB video card in a Windows 7 Ultimate x64 setup. If I only use one monitor, all is well. If I plug in a second DVI cable to the card, both monitors go dark. I can get one or the other to display, but only when it is the only one plugged into the card. I'm really hoping for a dual-monitor setup here as that was the point of the card. I'm using ATI Radeon HD 4600 Series video drivers dated 11/24/09 (8.681.0.0) which are the latest from their site and are supposed to work with Vista or Win7 x64. When the computer boots with both displays connected, both monitors display the inital bios and boot screens. The Win7 splash screen also displays, but by the time it goes to the login screen, one monitor is offline.

So I went and fired up my favorite partition manager - gparted, and told it to verify and repair the partition sdb1. This made gparted call e2fsck (version 1.42.4 (12-Jun-2012)) e2fsck -f -y -v /dev/sdb1 Although gparted called e2fsck with the "-v" option, sadly it doesn't show me the output of my e2fsck process (bugreport https://bugzilla.gnome.org/show_bug.cgi?id=467925 ) I started this whole thing on Sunday (2012-11-04_2200) evening, so about 48 hours ago, this is what htop says about it now (2012-11-06-1900): PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 3704 root 39 19 1560M 1166M 768 R 98.0 19.5 42h56:43 e2fsck -f -y -v /dev/sdb1 Now I found a few posts on the internet that discuss e2fsck running slow, for example: http://gparted-forum.surf4.info/viewtopic.php?id=13613 where they write that its a good idea to see if the disk is just that slow because maybe its damaged, and I think these outputs tell me that this is not the case in my case: kaefert@blechmobil:~$ sudo hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 3562 MB in 2.00 seconds = 1783.29 MB/sec Timing buffered disk reads: 82 MB in 3.01 seconds = 27.26 MB/sec kaefert@blechmobil:~$ sudo hdparm /dev/sdb /dev/sdb: multcount = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 364801/255/63, sectors = 5860533160, start = 0 However, although I can read quickly from that disk, this disk speed doesn't seem to be used by e2fsck, considering tools like gkrellm or iotop or this: kaefert@blechmobil:~$ iostat -x Linux 3.2.0-2-amd64 (blechmobil) 2012-11-06 _x86_64_ (2 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 14,24 47,81 14,63 0,95 0,00 22,37 Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 0,59 8,29 2,42 5,14 43,17 160,17 53,75 0,30 39,80 8,72 54,42 3,95 2,99 sdb 137,54 5,48 9,23 0,20 587,07 22,73 129,35 0,07 7,70 7,51 16,18 2,17 2,04 Now I researched a little bit on how to find out what e2fsck is doing with all that processor time, and I found the tool strace, which gives me this: kaefert@blechmobil:~$ sudo strace -p3704 lseek(4, 41026998272, SEEK_SET) = 41026998272 write(4, "\212\354K[_\361\3nl\212\245\352\255jR\303\354\312Yv\334p\253r\217\265\3567\325\257\3766"..., 4096) = 4096 lseek(4, 48404766720, SEEK_SET) = 48404766720 read(4, "\7t\260\366\346\337\304\210\33\267j\35\377'\31f\372\252\ffU\317.y\211\360\36\240c\30`\34"..., 4096) = 4096 lseek(4, 41027002368, SEEK_SET) = 41027002368 write(4, "\232]7Ws\321\352\t\1@[+5\263\334\276{\343zZx\352\21\316`1\271[\202\350R`"..., 4096) = 4096 lseek(4, 48404770816, SEEK_SET) = 48404770816 read(4, "\17\362r\230\327\25\346//\210H\v\311\3237\323K\304\306\361a\223\311\324\272?\213\tq \370\24"..., 4096) = 4096 lseek(4, 41027006464, SEEK_SET) = 41027006464 write(4, "\367yy>x\216?=\324Z\305\351\376&\25\244\210\271\22\306}\276\237\370(\214\205G\262\360\257#"..., 4096) = 4096 lseek(4, 48404774912, SEEK_SET) = 48404774912 read(4, "\365\25\0\21|T\0\21}3t_\272\373\222k\r\177\303\1\201\261\221$\261B\232\3142\21U\316"..., 4096) = 4096 ^CProcess 3704 detached around 16 of these lines every second, so 4 read and 4 write operations every second, which I don't consider to be a lot.. And finally, my question: Will this process ever finish? If those numbers from fseek (48404774912) represent bytes, that would be something like 45 gigabytes, with this beeing a 3 terrabyte disk, which would give me 134 days to go, if the speed stays constant, and e2fsck scans the disk like this completly and only once. Do you have some advice for me? I have most of the data on that disk elsewhere, but I've put a lot of hours into sorting and merging it to this disk, so I would prefer to getting this disk up and running again, without formatting it anew. I don't think that the hardware is damaged since the disk is only a few months and since I can't see any I/O errors in the dmesg output. UPDATE: I just looked at the strace output again (2012-11-06_2300), now it looks like this: lseek(4, 1419860611072, SEEK_SET) = 1419860611072 read(4, "3#\f\2447\335\0\22A\355\374\276j\204'\207|\217V|\23\245[\7VP\251\242\276\207\317:"..., 4096) = 4096 lseek(4, 43018145792, SEEK_SET) = 43018145792 write(4, "]\206\231\342Y\204-2I\362\242\344\6R\205\361\324\177\265\317C\334V\324\260\334\275t=\10F."..., 4096) = 4096 lseek(4, 1419860615168, SEEK_SET) = 1419860615168 read(4, "\262\305\314Y\367\37x\326\245\226\226\320N\333$s\34\204\311\222\7\315\236\336\300TK\337\264\236\211n"..., 4096) = 4096 lseek(4, 43018149888, SEEK_SET) = 43018149888 write(4, "\271\224m\311\224\25!I\376\16;\377\0\223H\25Yd\201Y\342\r\203\271\24eG<\202{\373V"..., 4096) = 4096 lseek(4, 1419860619264, SEEK_SET) = 1419860619264 read(4, ";d\360\177\n\346\253\210\222|\250\352T\335M\33\260\320\261\7g\222P\344H?t\240\20\2548\310"..., 4096) = 4096 lseek(4, 43018153984, SEEK_SET) = 43018153984 write(4, "\360\252j\317\310\251G\227\335{\214`\341\267\31Y\202\360\v\374\307oq\3063\217Z\223\313\36D\211"..., 4096) = 4096 So the numbers in the lseek lines before the reads, like 1419860619264 are already a lot bigger, standing for 1.29 terabytes if those numbers are bytes, so it doesn't seem to be a linear progress on a big scale, maybe there are only some areas that need work, that have big gaps in between them. UPDATE2: Okey, big disappointment, the numbers are back to very small again (2012-11-07_0720) lseek(4, 52174548992, SEEK_SET) = 52174548992 read(4, "\374\312\22\\\325\215\213\23\0357U\222\246\370v^f(\312|f\212\362\343\375\373\342\4\204mU6"..., 4096) = 4096 lseek(4, 46603526144, SEEK_SET) = 46603526144 write(4, "\370\261\223\227\23?\4\4\217\264\320_Am\246CQ\313^\203U\253\274\204\277\2564n\227\177\267\343"..., 4096) = 4096 so either e2fsck goes over the data multiple times, or it just hops back and forth multiple times. Or my assumption that those numbers are bytes is wrong. UPDATE3: Since it's mentioned here http://forums.fedoraforum.org/showthread.php?t=282125&page=2 that you can testisk while e2fsck is running, i tried that, though not with a lot of success. When asking testdisk to display the data of my partition, this is what I get: TestDisk 6.13, Data Recovery Utility, November 2011 Christophe GRENIER <[email protected]> http://www.cgsecurity.org 1 P Linux 0 4 5 45600 40 8 732566272 Can't open filesystem.

So I went and fired up my favorite partition manager - gparted, and told it to verify and repair the partition sdb1. This made gparted call e2fsck (version 1.42.4 (12-Jun-2012)) e2fsck -f -y -v /dev/sdb1 Although gparted called e2fsck with the "-v" option, sadly it doesn't show me the output of my e2fsck process (bugreport https://bugzilla.gnome.org/show_bug.cgi?id=467925 ) I started this whole thing on Sunday (2012-11-04_2200) evening, so about 48 hours ago, this is what htop says about it now (2012-11-06-1900): PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 3704 root 39 19 1560M 1166M 768 R 98.0 19.5 42h56:43 e2fsck -f -y -v /dev/sdb1 Now I found a few posts on the internet that discuss e2fsck running slow, for example: http://gparted-forum.surf4.info/viewtopic.php?id=13613 where they write that its a good idea to see if the disk is just that slow because maybe its damaged, and I think these outputs tell me that this is not the case in my case: kaefert@blechmobil:~$ sudo hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 3562 MB in 2.00 seconds = 1783.29 MB/sec Timing buffered disk reads: 82 MB in 3.01 seconds = 27.26 MB/sec kaefert@blechmobil:~$ sudo hdparm /dev/sdb /dev/sdb: multcount = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 364801/255/63, sectors = 5860533160, start = 0 However, although I can read quickly from that disk, this disk speed doesn't seem to be used by e2fsck, considering tools like gkrellm or iotop or this: kaefert@blechmobil:~$ iostat -x Linux 3.2.0-2-amd64 (blechmobil) 2012-11-06 _x86_64_ (2 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 14,24 47,81 14,63 0,95 0,00 22,37 Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 0,59 8,29 2,42 5,14 43,17 160,17 53,75 0,30 39,80 8,72 54,42 3,95 2,99 sdb 137,54 5,48 9,23 0,20 587,07 22,73 129,35 0,07 7,70 7,51 16,18 2,17 2,04 Now I researched a little bit on how to find out what e2fsck is doing with all that processor time, and I found the tool strace, which gives me this: kaefert@blechmobil:~$ sudo strace -p3704 lseek(4, 41026998272, SEEK_SET) = 41026998272 write(4, "\212\354K[_\361\3nl\212\245\352\255jR\303\354\312Yv\334p\253r\217\265\3567\325\257\3766"..., 4096) = 4096 lseek(4, 48404766720, SEEK_SET) = 48404766720 read(4, "\7t\260\366\346\337\304\210\33\267j\35\377'\31f\372\252\ffU\317.y\211\360\36\240c\30`\34"..., 4096) = 4096 lseek(4, 41027002368, SEEK_SET) = 41027002368 write(4, "\232]7Ws\321\352\t\1@[+5\263\334\276{\343zZx\352\21\316`1\271[\202\350R`"..., 4096) = 4096 lseek(4, 48404770816, SEEK_SET) = 48404770816 read(4, "\17\362r\230\327\25\346//\210H\v\311\3237\323K\304\306\361a\223\311\324\272?\213\tq \370\24"..., 4096) = 4096 lseek(4, 41027006464, SEEK_SET) = 41027006464 write(4, "\367yy>x\216?=\324Z\305\351\376&\25\244\210\271\22\306}\276\237\370(\214\205G\262\360\257#"..., 4096) = 4096 lseek(4, 48404774912, SEEK_SET) = 48404774912 read(4, "\365\25\0\21|T\0\21}3t_\272\373\222k\r\177\303\1\201\261\221$\261B\232\3142\21U\316"..., 4096) = 4096 ^CProcess 3704 detached around 16 of these lines every second, so 4 read and 4 write operations every second, which I don't consider to be a lot.. And finally, my question: Will this process ever finish?

Do you have some advice for me? I have most of the data on that disk elsewhere, but I've put a lot of hours into sorting and merging it to this disk, so I would prefer to getting this disk up and running again, without formatting it anew.

  • How many megabytes per second may I expect from a gigabit USB 2.0 network card under linux?

    - by Nakedible
    I'm interested in the actual real-word throughput attainable with an external 1000BaseT USB 2.0 network card under Linux. I have been able to attain 90 megabytes per second on a PCI-E interface, but the USB 2.0 bus has a theoretical limit of 480Mbit/s, and in practice less than 40 megabytes per second. Is the actual throughput attainable with such a card under linux 40, 30, 20, or even as low as 10 megabytes per second, eg. no better than a normal 100BaseT network card?

  • SQLS Timeouts - High Reads in Profiler

    - by lb01
    I've audited a SQLS2008 server with Profiler for one day.. the overhead didn't seem to trouble this new client my company has. They are using a legacy VB6 application as a front-end. They're experiencing timeouts once SQLS RAM usage is high. The server is currently running x64 sqls2008 on a VM with nearly 9 GB of RAM. SQL Server's 'max server memory option' is currently set to 6GB. I've put the results of the trace in a table and queried them using this query. SELECT TextData, ApplicationName, Reads FROM [TraceWednesday] WHERE textdata is not null and EventClass = 12 GROUP BY TextData, ApplicationName, Reads ORDER BY Reads DESC As I expected, some values are very high. Top Reads, in pages. 2504188 1965910 1445636 1252433 1239108 1210153 1088580 1072725 Am I correct in thinking that the top one (2504188 pages) is 20033504 KB, which then is roughly ~20'000 MB, 20GB? These queries are often executed and can take quite some time to run. Eventually RAM is used up because of the cache fattening, and timeouts occur once SQL cannot 'splash' pages in the buffer pool as much. Costs go up. Am I correct in my understanding? I've read that I should tune the associated T-SQL and create appropriate indices. Obviously cutting down the I/O would make SQL Server use less RAM. OR, maybe it might just slow down the process of chewing up the whole RAM. If a lot less pages are read, maybe it'll all run much better even when usage is high? (less time swapping, etc.) Currently, our only option is to restart SQL once a week when RAM usage is high, suddenly the timeouts disappear. SQL breathes again. I'm sure lots of DBAs have been in this situation.. I'm asking before I start digging out all of the bad T-SQL and put indices here and there, is there is something else I can do? Any advice except from what I know (not much yet..) Much appreciated. Leo.

  • Linux: find out what process is using all the RAM?

    - by Timur
    Before actually asking, just to be clear: yes, I know about disk cache, and no, it is not my case :) Sorry, for this preamble :) I'm using CentOS 5. Every application in the system is swapping heavily, and the system is very slow. When I do free -m, here is what I got: total used free shared buffers cached Mem: 3952 3929 22 0 1 18 -/+ buffers/cache: 3909 42 Swap: 16383 46 16337 So, I actually have only 42 Mb to use! As far as I understand, -/+ buffers/cache actually doesn't count the disk cache, so I indeed only have 42 Mb, right? I thought, I might be wrong, so I tried to switch off the disk caching and it had no effect - the picture remained the same. So, I decided to find out who is using all my RAM, and I used top for that. But, apparently, it reports that no process is using my RAM. The only process in my top is MySQL, but it is using 0.1% of RAM and 400Mb of swap. Same picture when I try to run other services or applications - all go in swap, top shows that MEM is not used (0.1% maximum for any process). top - 15:09:00 up 2:09, 2 users, load average: 0.02, 0.16, 0.11 Tasks: 112 total, 1 running, 111 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 4046868k total, 4001368k used, 45500k free, 748k buffers Swap: 16777208k total, 68840k used, 16708368k free, 16632k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 3214 ntp 15 0 23412 5044 3916 S 0.0 0.1 0:00.00 17m ntpd 2319 root 5 -10 12648 4460 3184 S 0.0 0.1 0:00.00 8188 iscsid 2168 root RT 0 22120 3692 2848 S 0.0 0.1 0:00.00 17m multipathd 5113 mysql 18 0 474m 2356 856 S 0.0 0.1 0:00.11 472m mysqld 4106 root 34 19 251m 1944 1360 S 0.0 0.0 0:00.11 249m yum-updatesd 4109 root 15 0 90152 1904 1772 S 0.0 0.0 0:00.18 86m sshd 5175 root 15 0 90156 1896 1772 S 0.0 0.0 0:00.02 86m sshd Restart doesn't help, and, by they way is very slow, which I wouldn't normally expect on this machine (4 cores, 4Gb RAM, RAID1). So, with that - I'm pretty sure that this is not a disk cache, who is using the RAM, because normally it should have been reduced and let other processes to use RAM, rather then go to swap. So, finally, the question is - if someone has any ideas how to find out what process is actually using the memory so heavily?

  • HP Proliant DL160 G6 - Hardware RAID card to get? [closed]

    - by zhuanyi
    I have bought a DL160 G6 server (Product number: 490427R-001 ) and it does not come with a hardware RAID card. I am trying to set up a VMWare Esxi server and as such I would need a hardware RAID card. I am just wondering if there is any card that would fit into the chassis? Would a P200i fits? How about a P400? Also, would there be any non-HP RAID card that will do the magic too? I have 4 SATA 160GB hard drives already plugged in. Thanks a lot!
