[zfs-discuss] ZFS, CIFS, slow write speed

Recently I've installed SXCE nv86 for the first time in hopes of getting rid of my linux file server and using Solaris and ZFS for my new file server. After setting up a simple ZFS mirror of 2 disks, I enabled smb and set about moving over all of my data from my old storage server. What I notice

Carson, are you sure about the patch number ? I have been unable to get a french support guy to find it. You are mentionning an "official" IDR patch for Solaris 10 x86, update 4, aren't you ? Thanks. Xavier. This message posted from opensolaris.org __

[zfs-discuss] UFS or ZFS for MYSQL and APACHE web server data and Database

I have two 200GB ISCSI LUN's setup on each X4600 M2 running Solaris 10 X86 update 4. The data on these ISCSI disks for one server will be Apache and on the other server MYSQL. My question is should I setup these disks as a ZFS Pool filesystem or as a UFS soft partition (eventually the LUN wil

[zfs-discuss] panic on zfs scrub on builds 79 & 86

This just started happening to me. It's a striped non mirrored pool (I know I know). A zfs scrub causes a panic under a minute. I can also trigger a panic by doing tars etc. x86 64-bit kernel ... any ideas? Just to help rule out some things, I changed the motherboard, memory and cpu and it still

Re: [zfs-discuss] zfs data corruption

Just to clarify this post. This isn't data I care about recovering. I'm just interested in understanding how zfs determined there was data corruption when I have checksums disabled and there were no non-retryable read errors reported in the messages file. On Wed, Apr 23, 2008 at 9:52 PM, Victor En

Re: [zfs-discuss] zfs write cache enable on boot disks ?

What is the reasoning behind ZFS not enabling the write cache for the root pool? Is there a way of forcing ZFS to enable the write cache? Thanks Andrew. This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.o

Re: [zfs-discuss] zfs write cache enable on boot disks ?

Just to clarify a bit, ZFS will not enable the write cache for the root pool. That said, there are disk drives which have the write cache enabled by default. That behavior remains unchanged. - George George Wilson wrote: > Unfortunately not. > > Thanks, > George > > Par Kansala wrote: > >> H
