The system remained "up" until I tried to restart the afs client and server...
/dev/sdb2 is trashed (/usr/vice/cache) so I'll mount a loopback device fir the time being. tedc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ted creedon Sent: Friday, August 12, 2005 12:54 PM Cc: openafs-info@openafs.org Subject: RE: [OpenAFS] Crash testing OpenAFS Not good news: cp -rvp /afs/.bigcell/foo/* /afs/.home.ted-doris.fam/bar #doesn't work Where bigcell is 1.2.11 and home is 1.3.87 1. The transfer stops for no apparent reason after transferring for quite a while. Looking at TOP - rxlistener, etc just disappear. The OS and afs server/clients remained up. 2. Its doesn't appear to be the filenames. I built a replica of the filesystem by making 1410 directories (with some weird names too) and populating 24000 zero length files using touch. This structure transferred in 38 sec. 3. It appears that the crashing is related to actual stress under load i.e. when the 24000 files contain actual data. 4. cp -rvp /afs/.bigcell/foo/* /afs/.bigcell/bar #does seem to work. 5. I'll probably run tripwire on 4 this evening. tedc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ted creedon Sent: Friday, August 12, 2005 8:46 AM Cc: openafs-info@openafs.org Subject: RE: [OpenAFS] Crash testing OpenAFS -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of chas williams - CONTRACTOR Sent: Friday, August 12, 2005 3:23 AM To: ted creedon Cc: openafs-info@openafs.org Subject: Re: [OpenAFS] Crash testing OpenAFS In message <[EMAIL PROTECTED]>,"ted creedon" writes: >A simple cp -rpv /afs/.bigcell/foo /afs/.home-ted-doris.fam/bar hangs >the system so badly Linux won't even "halt". that sounds simple, but what are foo and bar? >> foo= 4.8GB backup of a windows drive on a 1.2.11 AFS server bar= >> 8000000 Kblock mount into a volume on a 1.3.87 server i cant duplicate this test unless i have a little more information. does afs break if you cp -rpv /afs/.bigcell/foo /afs/.bigcell/bar? >>No. It runs fine if kept on the Linux 1.2.11 server/client does it run for a little bit and stop? >>No. Takes a long while. does it hang immediately? >>No is there a particular file that stops it every time? >> This is possibly the case.
