Kory, I'm sorry that you had to go through this. We're all working very hard to make ZFS better for everyone. We've noted this problem on the ZFS Best Practices wiki to try and help avoid future problems until we can get the quotas issue resolved. -- richard Kory Wheatley wrote: Richard, I a

I think this is a systems engineering problem, not just a ZFS problem. Few have bothered to look at mount performance in the past because most systems have only a few mounted file systems[1]. Since ZFS does file system quotas instead of user quotas, now we have the situation where there could be

Hi Kory - Your problem came our way through other Sun folks a few days ago, and I wish I had that magic setting to help, but the reality is that I'm not aware of anything that will improve the time required to mount 12k file systems. I would add (not that this helps) that I'm not convinced this

The reason for this question is we currently have our disk setup in a hardware raid5 on a EMC device and these disks are configured as a zfs file system. Would it benefit us to have the disk be setup as a raidz along with the hardware raid 5 that is already setup too? Or with this double raid
