I have a little question about user properties, I have two filesystems: rpool/export/home/luca and rpool/export/home/luca/src in this two I have one user property, setted with: zfs set net.morettoni:test=xyz rpool/export/home/luca zfs set net.morettoni:test=123 rpool/export/home/luca/src now I need to *clear* (remove) the property from rpool/export/home/luca/src filesystem, but if I use the

Hi, one quick&dirty way of backing up a pool that is a mirror of two devices is to zpool attach a third one, wait for the resilvering to finish, then zpool detach it again. The third device then can be used as a poor man''s simple backup. Has anybody tried it yet with a striped mirror? What if the pool is composed out of two mirrors? Can I attach devices to both mirrors, let them

Hi folks, I would appreciate it if someone can help me understand some weird results I''m seeing with trying to do performance testing with an SSD offloaded ZIL. I''m attempting to improve my infrastructure''s burstable write capacity (ZFS based WebDav servers), and naturally I''m looking at implementing SSD based ZIL devices. I have a test machine with the

Experts, I''m installing Oracle 9i on Solaris 10 11/06(update 3),I created some zfs volumes which will be used by oracle data file,as: # zfs create -V 200m ora_pool/controlfile01_200m # zfs create -V 800m ora_pool/system_800m ... # ls -l /dev/zvol/rdsk/ora_pool lrwxrwxrwx 1 root root 39 Apr 11 12:23 controlfile01_200m -> ../../../../devices/pseudo/zfs at 0:1c,raw

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. I am trying to move the root volume from an existing svm mirror to a zfs root. The machine is a Sun V880 (SPARC) running nv_96, with OBP version 4.22.34 which is AFAICT the latest. The svm mirror was constructed as follows / d4 m 18GB d14 d14 s 35GB c1t0d0s0 d24 s 35GB c1t1d0s0 swap d3

Hi all, I have a pool called tank/home/foo and I want to rename it to tank/home/bar. What''s the best way to do this (the zfs and zpool man pages don''t have a "rename" option)? One way I can think of is to create a clone of tank/home/foo called tank/home/bar, and then destroy the former. Is that the best (or even only) way? TIA, -- Rich Teer, SCSA, SCNA, SCSECA,

I have an Ultra 10 client running Sol10 U3 that has a zfs pool set up on the extra space of the internal ide disk. There''s just the one fs and it is shared with the sharenfs property. When this system reboots nfs/server ends up getting disabled and this is the error from the SMF logs: [ Apr 16 08:41:22 Executing start method ("/lib/svc/method/nfs-server start") ] [ Apr 16

Is it possible to gracefully and permanently remove a vdev from a pool without data loss? The type of pool in question here is a simple pool without redundancies (i.e. JBOD). The documentation mentions for instance offlining, but without going into the end results of doing that. The thing I''m looking for is an option to evacuate, for the lack of a better word, the data from a specific

My understanding is that if I "zfs set checksum=<different>" to change the algorithm that this will change the checksum algorithm for all FUTURE data blocks written, but does not in any way change the checksum for previously written data blocks. I need to corroborate this understanding. Could someone please point me to a document that states this? I have searched and searched

Zpool split is a wonderful feature and it seems to work well, and the choice of which disk got which name was perfect! But there seems to be an odd anomaly (at least with b132) . Started with c0t1d0s0 running b132 (root pool is called rpool) Attached c0t0d0s0 and waited for it to resilver Rebooted from c0t0d0s0 zpool split rpool spool Rebooted from c0t0d0s0, both rpool and spool were mounted

The time has come to review the current Contributor and Core contributor grants for ZFS. Since all of the ZFS core contributors grants are set to expire on 02-24-2009 we need to renew the members that are still contributing at core contributor levels. We should also add some new members to both Contributor and Core contributor levels. First the current list of Core contributors: Bill

All; I am deeply sorry if this topic has been rehashed, checksummed, de-duplicated and archived before. But I just need a small clarification. /etc/sfw/smb.conf is necessary only for smb/server to function properly but is smb/server SMF service necessary for ZFS sharesmb to work I am trying to setup an open solaris file server acting as a Windows PDC with SAMBA/LDAP integration on the open

hi everyone, I am planning on creating a local SAN via NFS(v4) and several redundant nodes. I have been using DRBD on linux before and now am asking whether some of you have experience on on-demand network filesystem mirrors. I have yet little Solaris sysadmin know how, but i am interesting whether there is an on-demand support for sending snapshots. I.e. not via a cron job, but via a

In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz storage pool and then shelved the other two for spares. One of the disks failed last night so I shut down the server and replaced it with a spare. When I tried to zpool replace the disk I get: zpool replace tank c10t0d0 cannot replace c10t0d0 with c10t0d0: device is too small The 4 original disk partition tables look like

This question is concerning ZFS. We have a Sun Fire V890 attached to a EMC disk array. Here''s are plan to incorporate ZFS: On our EMC storage array we will create 3 LUNS. Now how would ZFS be used for the best performance? What I''m trying to ask is if you have 3 LUNS and you want to create a ZFS storage pool, would it be better to have a storage pool per LUN or combine the 3

Hi all, I''ll attach a new version zfs-auto-snapshot including some more improvements, and probably some new bugs. Seriously, I have tested it, but certainly not all functionality, so please let me know about any (new) problems you come across. Except from the change log: - Added support to schedule using at(1), see README.zfs-auto-snapshot.txt - take_snapshot will only run if
