Can anyone comment on Solaris with zfs on HP systems? Do things work reliably? When there is trouble how many hoops does HP make you jump through (how painful is it to get a part replaced that isn't flat out smokin')? Have you gotten bounced between vendors? Thanks, Chris Erik Trimble wrote:

[zfs-discuss] zpool iostat / how to tell if your iop bound

2010-03-10 Thread Chris Banal
What is the best way to tell if your bound by the number of individual operations per second / random io? zpool iostat has an operations column but this doesn't really tell me if my disks are saturated. Traditional iostat doesn't seem to be the greatest place to look when utilizing zfs. Thanks,

Assuming no snapshots. Do full backups (ie. tar or cpio) eliminate the need for a scrub? Thanks, Chris ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] improve meta data performance

2010-02-18 Thread Chris Banal
We have a SunFire X4500 running Solaris 10U5 which does about 5-8k nfs ops of which about 90% are meta data. In hind sight it would have been significantly better to use a mirrored configuration but we opted for 4 x (9+2) raidz2 at the time. We can not take the downtime necessary to change the

2009-09-30 Thread Chris Banal
We have a production server which does nothing but nfs from zfs. This particular machine has plenty of free memory. Blogs and Documentation state that zfs will use as much memory as is necessary but how is necessary calculated? If the memory is free and unused would it not be beneficial to

[zfs-discuss] NLM_DENIED_NOLOCKS Solaris 10u5 X4500

This was previously posed to the sun-managers mailing list but the only reply I received recommended I post here at well. We have a production Solaris 10u5 / ZFS X4500 file server which is reporting NLM_DENIED_NOLOCKS immediately for any nfs locking request. The lockd does not appear to be busy

[zfs-discuss] Directory size value

2009-09-21 Thread Chris Banal
It appears as though zfs reports the size of a directory to be one byte per file. Traditional file systems such as ufs or ext3 report the actual size of the data needed to store the directory. This causes some trouble with the default behavior of some nfs clients (linux) to decide to to use a
