In another thread recursive snapshot creation was found atomic so that it is done quickly, and more important, all at once or nothing at all. Do you know if recursive destroying and renaming of snapshots are atomic too? Regards Henrik Heino

Hello, I want to setup an opensolaris for centralized storage server, using ZFS as the underlying FS, on a RAID 10 SATA disks. I will export the storage blocks using ISCSI to RHEL 5 (less than 10 clients, and I will format the partition as EXT3) I want to ask... 1. Is this setup suitable for mission critical use now? 2. Can I use LVM with this setup? Currently we are using NFS as the

This is possibly the dumbest question I have asked ever, but how do you set ACLs on files within a ZFS filesystem? Trying to use setfacl(1) diverts me to the acl(5) manpage; well, I know that I need to use NFSv4 style ACLs, but where is the utility to do so? This is on Solaris 10 Update 2. Thanks, Ceri -- That must be wonderful! I don''t understand it at all.

Hi, I was discussing the common practice of disk eradication used by many firms for security. I was thinking this may be a useful feature of ZFS to have an option to eradicate data as its removed, meaning after the last reference/snapshot is done and a block is freed, then write the eradication patterns back to the removed blocks. By any chance, has this been discussed or considered before?

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

Hi guys, I am about to reshape my data spool and am wondering what performance diff. I can expect from the new config. Vs. The old. The old config. Is a pool of a single vdev of 8 disks raidz2. The new pool config is 2vdev''s of 7 disk raidz2 in a single pool. I understand it should be better with higher io throughput....and better read/write rates...but interested to hear the science

I thought I recalled reading somewhere that in the situation where you have several zfs filesystems under one top level directory like this: rpool rpool/ROOT/osol-112 rpool/export rpool/export/home rpool/export/home/reader you could do a shapshot encompassing everything below zpool instead of having to do it at each level. (Maybe it was in a dream...)

I''m currently planning on running FreeBSD with ZFS, but I wanted to double-check how much memory I''d need for it to be stable. The ZFS wiki currently says you can go as low as 1 GB, but recommends 2 GB; however, elsewhere I''ve seen someone claim that you need at least 4 GB. Does anyone here know how much RAM FreeBSD would need in this case? Likewise, how much RAM

Starting from this thread: http://www.opensolaris.org/jive/thread.jspa?messageID=118786&#118786 I would love to have the possibility to set an ISCSI alias when doing an shareiscsi=on on ZFS. This will greatly facilate to identify where an IQN is hosted. the ISCSI alias is defined in rfc 3721 e.g. http://www.apps.ietf.org/rfc/rfc3721.html#sec-2 and the CLI could be something like: zfs set

Hi all! I need a non-root user to be able to perform zfs snapshots and rollbacks. Does anybody know what privileges that should be specified in /etc/user_attr ? Best regards, Lars-Erik Bj?rk

Hi Folks.. I have a system that was inadvertently left unmirrored for root. We were able to add a mirror disk, resilver, and fix the corrupted files (nothing very interesting was corrupt, whew), but zpool status -v still shows errors.. Will this self correct when we replace the degraded disk and resilver? Or is there something else that I''m not finding that I need to do to clean up?

Hi, my system (solaris b77) was physically destroyed and i loosed data saved in a zpool mirror. The only thing left is a dettached vdev from the pool. I''m aware that uberblock is gone and that i can''t import the pool. But i still hope their is a way or a tool (like tct http://www.porcupine.org/forensics/) i can go too recover at least partially some data) thanks in advance for

Sorry for an off-topic question, but anyone knows how to make network configuration (done with ifconfig/route add) sticky in nexenta core/napp-it? After reboot system reverts to 0.0.0.0 and doesn''t listen to /etc/defaultrouter Thanks.

Are any plans for an API that would allow ZFS commands including snapshot/rollback integrated with customer''s application? Thanks, Cherry

Hi I''m running OpenSolaris 148 on a few boxes, and newer boxes are getting installed as we speak. What would you suggest for a good SLOG device? It seems some new PCI-E-based ones are hitting the market, but will those require special drivers? Cost is obviously alsoo an issue here....

Hello, I am curious to know if there is an easy way to guess or identify the device names of disks. Previously the /dev/dsk/c0t0d0s0 system made sense to me... I had a SATA controller card with 8 ports, and they showed up with the numbers 1-8 in the "t" position of the device name. But I just built a new system with two LSI SAS HBAs in it, and my device names are along the lines of:
