Re: [OpenAFS] Poor performance on new ZFS-based file server

2007-07-11 Thread Dale Ghent
Also, Brian, how much RAM does your box have? To expound on Rob's first point, the spindle count of a RAIDZ (or Z2) set is important. It's generally urged to keep the disks that comprise a raidz(2) set in the single digits and no more than 10 or so (note this is not per pool, but per set.

Re: [OpenAFS] Poor performance on new ZFS-based file server

2007-07-11 Thread Robert Banz
A couple things to check, Brian... 1) How large is your RAID-Z2 pool (# of spindles)? If it's rather large (say, above 8), you might be running into problems from that. 2) Check to see if your fileserver process is fully resident in memory (not swapped out.) ZFS's ARC can get VERY greedy

[OpenAFS] Poor performance on new ZFS-based file server

Hello, I've been getting intermittant reports of slow read performance on a new AFS file server that I recently set up based on ZFS. It is using locally attached disks in a RAID-Z2 (double parity) configuration. I was wondering if anyone might be able to provide any ideas for tuning / investigat

[OpenAFS] GCPAGs = 8

2007-07-11 Thread Nate Gordon
I'm currently trying to debug some mysterious server crashes and am curious about how the sysctl var afs.GCPAGs works. From what I've gleaned from the archives/code is that GCPAGs = 1 allows the garbage collection of pags, anything else prevents it. Is this correct? Next why would my GCPAGs be

Re: [OpenAFS] Restore primary from replica server

2007-07-11 Thread Kim Kimball
AFS doesn't require a 'primary server' nor does it require segregation of RW volumes and RO volumes. It will help to know what makes a server your 'primary.' That being said, some sites do consider a specific AFS file server to be their 'primary.' This may be for non-AFS reasons. For example
