[zfs-code] are there any workarounds for (low memory) deadlocks?
Hi! We''re running Solaris10u4 here on a Sun Fire 2200 (x86/Opteron) with 8 GB RAM, and after a long time of problems I''m about to give up our zfs installation (on a simple scsi hardware raid) because of massive problems with (low memory?) deadlocks - even a simple ''zfs list'' sometimes locks the zfs-system for minutes, especially when there''s some traffic (it''s a samba-box). I''m sorry for not giving a more detailed description but I guess some people know this problem - I just couldn''t find any solution or workaround anywhere. Could be (i.e.) the same as: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6628833 http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6457639 So, is there any workaround for this (changing the arc cache setting in /etc/system is at least useless here, adding 4 GB RAM didn''t help either) or will there be a solution/patch for it in the (near) future?

Sounds like you''ve got IO issues not memory issues. -J On Jan 18, 2008 10:44 AM, Jochem Ippers <jochem_ippers at web.de> wrote:> Hi! > We''re running Solaris10u4 here on a Sun Fire 2200 (x86/Opteron) with 8 GB RAM, and after a long time of problems I''m about to give up our zfs installation (on a simple scsi hardware raid) because of massive problems with (low memory?) deadlocks - even a simple ''zfs list'' sometimes locks the zfs-system for minutes, especially when there''s some traffic (it''s a samba-box). > > I''m sorry for not giving a more detailed description but I guess some people know this problem - I just couldn''t find any solution or workaround anywhere. > Could be (i.e.) the same as: > http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6628833 > http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6457639 > > So, is there any workaround for this (changing the arc cache setting in /etc/system is at least useless here, adding 4 GB RAM didn''t help either) or will there be a solution/patch for it in the (near) future? > > Greetings from Aachen, germany > Jochem Ippers > -- > This messages posted from opensolaris.org > _______________________________________________ > zfs-code mailing list > zfs-code at opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-code >
