Re: [zfs-discuss] s10u6--will using disk slices for zfs logs improve nfs performance?

I wouldn't expect any improvement using a separate disk slice for the Intent Log unless that disk was much faster and was otherwise largely idle. If it was heavily used then I'd expect quite the performance degradation as the disk head bounces around between slices. Separate intent logs are really

[zfs-discuss] s10u6--will using disk slices for zfs logs improve nfs performance?

I've got an X4500/thumper that is mainly used as an NFS server. It has been discussed in the past that NFS performance with ZFS can be slow (when running "tar" to expand an archive with lots of files, for example.) My understanding is the reason that zfs/nfs is slow in this case is because it i

Re: [zfs-discuss] Pool corruption avoidance

Same situation here. We are just planning a new 200TB+ NFS storage pool and a bunch of x4100+j4400 would be great (j4400 is missing multipath??) and cheap but we already lost many zpools in the last 2 years and so ZFS won't be an option. At this time we are using ZFS only in our central backup

Re: [zfs-discuss] zvol snapshot at size 100G

Just to try this out, I created a 9g zpool and a 5g volume in that zpool. Then I used dd to write to every block of the volume. Taking a snapshot of the volume at that point attempts to reserve an additional 5g, which fails. With 1g volumes we see it in action: bash-3.00# zpool create tank c0

[zfs-discuss] Best SXCE version for ZFS Home Server

Hi everyone, I will shortly install a ZFS Home Server and I am wondering which version I should install. I will use zones on my server and heavily use zone cloning, so I think it rules out S10U6. I also ruled out Indiana because of the lack of "normal" zones. So I will be using SXCE. Which version
