Re: [zfs-discuss] COMSTAR iSCSI and two Windows computers

2010-06-20 Thread Roy Sigurd Karlsbakk
- Original Message - Thanks guys - I will take a look at those clustered file systems. My goal is not to stick with Windows - I would like to have a Storage pool for XenServer (free) so that I can have guests, but using a storage server (Opensolaris - ZFS) as the iSCSI storage pool.

[zfs-discuss] One dataset per user?

2010-06-20 Thread Roy Sigurd Karlsbakk
Hi all We're working on replacing our current fileserver with something based on either Solaris or NexentaStor. We have about 200 users with variable needs. There will also be a few common areas for each department and perhaps a backup area. I think these should be separated with datasets, for

TBH write amp was not considered, but since I've never heard of a write amp over 1.5, for my purposes on the 256gb drives they still last welll over the required 5 year life span. Again it does hurt a lot when your using smaller drives that less space available for wear leveling. I suppose

[zfs-discuss] zfs periodic writes on idle system [Re: Getting desktop to auto sleep]

2010-06-20 Thread Jürgen Keil
Why does zfs produce a batch of writes every 30 seconds on opensolaris b134 (5 seconds on a post b142 kernel), when the system is idle? On an idle OpenSolaris 2009.06 (b111) system, /usr/demo/dtrace/iosnoop.d shows no i/o activity for at least 15 minutes. The same dtrace test on an idle b134

[zfs-discuss] Scrub time dramaticy increased

2010-06-20 Thread bonso
Hello all, I recently noticed that my storage pool has started to take a lot of time finishing a scrub, approximately the final 10% takes 30m to finish while the previous 90 are done is as many minutes. The 'zpool status' command does however not change its estimated remaining time. Currently
