adrianz Posted October 13, 2012 Share Posted October 13, 2012 I installed new disk (WD20EARX) yesterday evening, started new screen session, then preclear script and then went to bed. In the morning I've noticed that all my drives (except parity) were spun up and my syslog was (and still constantly is) littered with these same lines: Oct 13 08:47:08 Tower kernel: smbd: page allocation failure: order:4, mode:0x4020 Oct 13 08:47:08 Tower kernel: Pid: 21703, comm: smbd Not tainted 3.4.11-unRAID #1 Oct 13 08:47:08 Tower kernel: Call Trace: Oct 13 08:47:08 Tower kernel: [] warn_alloc_failed+0xbd/0xcf Oct 13 08:47:08 Tower kernel: [] __alloc_pages_nodemask+0x47c/0x4a5 Oct 13 08:47:08 Tower kernel: [] __get_free_pages+0xf/0x21 Oct 13 08:47:08 Tower kernel: [] __kmalloc+0x2c/0xf0 Oct 13 08:47:08 Tower kernel: [] pskb_expand_head+0xc1/0x224 Oct 13 08:47:08 Tower kernel: [] ?

Manually spinning down disks helps for few minutes or few hours, but sooner or later this block of log reappears and disks spin up (all except parity). I've tried turning off spin-up groups (because I had problem with strange spin-ups before on 4.7 and that helped), changing chache_dirs settings (because it looks like there's something eating a lot of memory and cache_dirs was all I could think of) and restarting Samba by changing mover settings (because there is something about smbd failure in the first line). That can also be caused by preclear script (latest version 1.13), but it's still few hours until it ends or my screen installation (I've downloaded screen, aaa_terminfo and utempter packages and put them in flash/extra folder). But the funny thing is, not counting spin ups, everything is working fine - streming media from the array works, same as preclear script, WebGUI, I have telnet access, yet there is clearly something wrong going on :-( Please advise.

mejutty Posted December 5, 2012 Share Posted December 5, 2012 Did you get anywhere with this. I just went to clear some 4tb hd's and I get the same thing as soon as I run the preclear smbd: page allocation failures. Quote Link to comment
dgaschk Posted December 5, 2012 Share Posted December 5, 2012 Does this happen with no add-ons? Quote Link to comment
bcbgboy13 Posted December 5, 2012 Share Posted December 5, 2012 You are using RC8a but have you manually installed the new Samba 3.6.8 (the one in the Unraid package is 3.6.7 and it is buggy) Quote Link to comment
jangjong Posted December 5, 2012 Share Posted December 5, 2012 I had a similar issue.. Then found this thread: http://lime-technology.com/forum/index.php?topic=3999.0 First, run this command to see the current "min_free_kbytes" value. cat /proc/sys/vm/min_free_kbytes and go to this page http://dd.qc.ca/people.redhat.com/kernel/min_free_kbytes.html and figure out what it should be.. then run this echo #### > /proc/sys/vm/min_free_kbytes #### should be the number shown for your memory from the web page above. For example, if you have 4GB of ram, #### should be 8192 I have 16GB of ram. I think my original value was maybe somewhere in 3000, forgot to write it down.. I set min_free_kbytes to 16384. Also added that command line to go file to set that everytime it boots up. After that, I am not getting any kind of page allocation error in my log file.. I posted this another thread, but can someone explain what min_free_kbytes is for? and why unraid doe not set it to the default value as shown in that web page? Quote Link to comment
mejutty Posted December 5, 2012 Share Posted December 5, 2012 Did not try without addons as I have never not had them running and I have never seen the errors while pre-clearing before. i have the latest rc and have installed the latest samba. I have just put the min freekbytes command in and tested again did not see error do will monitor.

mejutty Posted December 6, 2012 Share Posted December 6, 2012 Nope came back as soon as I started transfering a file to my windows machine via smb. 2 Preclears still going. If I stop the preclears no errors at all no matter what I transfer. If I read the free command correclty I have affectivly 2.8Gb of ram cached that can be allocated as required so why the out of ram errors?? This time looks both an smb error as well as a unraid error. root@Tower:/# free -l total used free shared buffers cached Mem: 3888632 3846724 41908 0 711940 2842224 Low: 870192 854104 16088 High: 3018440 2992620 25820 -/+ buffers/cache: 292560 3596072 Swap: 0 0 0 Dec 6 09:29:48 Tower kernel: smbd: page allocation failure: order:5, mode:0x4020 Dec 6 09:29:48 Tower kernel: Pid: 9720, comm: smbd Not tainted 3.4.11-unRAID #1 (Errors) Dec 6 09:29:48 Tower kernel: Call Trace: (Errors) Dec 6 09:29:48 Tower kernel: [<c1062eb6>] warn_alloc_failed+0xbd/0xcf (Errors) Dec 6 09:29:48 Tower kernel: [<c106372e>] __alloc_pages_nodemask+0x47c/0x4a5 (Errors) Dec 6 09:29:48 Tower kernel: [<c10637ad>] __get_free_pages+0xf/0x21 (Errors) Dec 6 09:29:48 Tower kernel: [<c10821c8>] __kmalloc+0x2c/0xf0 (Errors) Dec 6 09:29:48 Tower kernel: [<c12a0072>] pskb_expand_head+0xc1/0x224 (Errors) Dec 6 09:29:48 Tower kernel: [<c12a054b>] __pskb_pull_tail+0x41/0x21e (Errors) Dec 6 09:29:48 Tower kernel: [<c12a4421>] ?

mejutty Posted December 6, 2012 Share Posted December 6, 2012 At this stage it only appears to be triggered by SMB access. ie I have plex sick and sab running it can be serving up movies via plex client downloading unpacking stuff from newsgoups and I see no errors as soon as I transfer via smb I get the errors.

jangjong Posted December 6, 2012 Share Posted December 6, 2012 Actually, many people recommend setting min_free_kbytes value to 65536. http://www.acc.umu.se/~maswan/linux-netperf.txt http://russ.garrett.co.uk/2009/01/01/linux-kernel-tuning/ http://askubuntu.com/questions/41778/computer-freezing-on-almost-full-ram-possibly-disk-cache-problem I'd try that and see if that changes anything.. I say this because I did too get this error whenever I have an activity through smb (read/write) while running pre_clear in screen Quote Link to comment
mejutty Posted December 7, 2012 Share Posted December 7, 2012 Ahh 64Mb seemed to do the trick, read write and 2 preclears running via screen all good no errors. Thank you muchly will add that to my go file. Quote Link to comment
jangjong Posted December 7, 2012 Share Posted December 7, 2012 oh good! so min_free_kbytes does fix this page location errros.. good to know. .good to know lol im gonna set mine to 65536 heh Quote Link to comment
mejutty Posted December 7, 2012 Share Posted December 7, 2012 My pre-clears just finished so I tested that the new line in my go file worked which it did from a reboot. I have a no correct parity check running as I am about to replace my 3tb parity with a 4tb parity. After parity has been built on this new parity drive I will be adding a new 4tb drive into the array then running a preclear on the old 3tb parity drive, during this preclear run I will couple of check that I get no more errors by reading a writing some blu-ray iso files during preclear and see what transpires. Thank you muchly for the info. Quote Link to comment
mejutty Posted December 8, 2012 Share Posted December 8, 2012 I can confirm after the modification above I have run a preclear while I read 100Gb from the array and wrote 25gb to the array and not a single error. 4tb drive is now parity with another 4tb drive as data drive in the array. old 3tb parity is currenlty preclearing although it must be missreporting as it is currenlty doing the zero writes and is reporting 316911968256 bytes (317 GB) copied, 1624.12 s, 195 MB/s Will see how it goes.
