similar to: ZFS/NFS - SC 3.2 and AVS - HOWTO [SOLVED]

Hello all.. Using dtrace on solaris 10, i could investigate a performance issue with the sincronization of some files on a ZFS filesystem. I have started the follow rsync command (inside a gnome-terminal): /opt/sfw/bin/rsync -av -e ssh user@IP:/DirA/DirB . The current directory(.), was a ZFS pool with two SATA discs (mirror)... The performance was terrible. After some tests with raid0,

We are currently running sun cluster 3.2 on solaris 10u3. We are using ufs/vxvm 4.1 as our shared file systems. However, I would like to migrate to HA-NFS on ZFS. Since there is no conversion process from UFS to ZFS other than copy, I would like to migrate on my own time. To do this I am planning to add a new zpool HAStoragePlus resource to my existing HA-NFS resource group. This way I can migrate

Hi All, Two and three-node clusters with SC3.2 and S10u3 (120011-14). If a node is rebooted when using SCSI3-PGR the node is not able to take the zpool by HAStoragePlus due to reservation conflict. SCSI2-PGRE is okay. Using the same SAN-LUN:s in a metaset (SVM) and HAStoragePlus works okay with PGR and PGRE. (both SMI and EFI-labled disks) If using scshutdown and restart all nodes then it will

I have a test cluster running HA-NFS that shares both ufs and zfs based file systems. However, the behavior that I am seeing is a little perplexing. The Setup: I have Sun Cluster 3.2 on a pair of SunBlade 1000''s connecting to two T3B partner groups through a QLogic switch. All four bricks of the T3B are configured as RAID-5 with a hot spare. One brick from each pair is mirrored with VxVM

Issues with ZFS and Sun Cluster If a cluster node crashes and HAStoragePlus resource group containing ZFS structure (ie. Zpool) is transitioned to a surviving node, the zpool import can cause the surviving node to panic. Zpool was obviously not exported in controlled fashion because of hard crash. Storage structure is - HW RAID protected LUN from array. Zpool build on single HW LUN. Zpool created

Hello all, Sorry if you think that question is stupid, but i need to ask.. Imagine a normal situation on a NFS server with "N" client nodes. The objects of the shares is software (/usr/ for instance), and the admin wants to make available new versions of a few packages. So, would be nice if the admin could associate a NFS share and a ZFS snapshot? I mean, the admin have the option

Hello all, I''m looking for answers about a question that i did post on ZFS/UFS discuss... without success, now i''m here to see your points. Any tips? As you know, i''m making some "screencasts" about a few solaris features. That screencasts is one point of many tests that i''m making with solaris 10. Now, with some tests with dtrace, i have saw a

Hello, I''m trying to implement a NAS server with solaris/NFS and, of course, ZFS. But for that, we have a little problem... what about the /home filesystem? I mean, i have a lot of linux clients, and the "/home" directory is on a NFS server (today, linux). I want to use ZFS, and change the "directory" home like /home/leal, to "filesystems" like /home/leal

Hello all... I''m migrating a nfs server from linux to solaris, and all clients(linux) are using read/write block sizes of 8192. That was the better performance that i got, and it''s working pretty well (nfsv3). I want to use all the zfs'' advantages, and i know i can have a performance loss, so i want to know if there is a "recomendation" for bs on nfs/zfs, or

Hello all, I have a doubt that i think you hackers of rsync has the answer. ;-) I have make this post on my blog: http://www.posix.brte.com.br/blog/?p=312 to start a serie about the copy-on-write semantics of ZFS. In my test "VI" did rewrite the whole file just for change 3 bytes, so the whole file was reallocated. What i want to know from you is about the techniques used by rsync

Hi, I''m struggling to get a stable ZFS replication using Solaris 10 110/06 (actual patches) and AVS 4.0 for several weeks now. We tried it on VMware first and ended up in kernel panics en masse (yes, we read Jim Dunham''s blog articles :-). Now we try on the real thing, two X4500 servers. Well, I have no trouble replicating our kernel panics there, too ... but I think I

Hello all, I was thinking if such scenario could be possible: 1 - Export/import a ZFS filesystem in two solaris servers. 2 - Export that filesystem (NFS). 3 - Mount that filesystem on clients in two different mount points (just to authenticate in both servers/UDP). 4a - Use some kind of "man-in-the middle" to auto-balance the connections (the same IP on servers) or 4b - Use different

Hello! Our company have 2 sun 7110 with the following configuration: Primary: 7110 with 2 qc 1.9ghz HE opterons and 32GB ram 16 2.5" 10Krpm sas disc (2 system, 1 spare) a pool is configured from the rest so we have 13 active working discs in raidz-2 (called main) there is a sun J4200 jbod connected to this device with 12x750GB discs with 1 spare and 11active discs there is another pool

Greetings all. I am facing serious problems running ZFS on a storage server assembled out of commodity hardware that is supposed to be Solaris compatible. Although I am quite familiar with Linux distros and other unices, I am new to Solaris so any suggestions are highly appreciated. First I tried SXDE 1/08 creating the following pool: -bash-3.2# zpool status -v tank pool: tank state:

I want to test out my first V1.2 Dovecot (upgraded from V1.1) instance. What I have in mind to do is to run it on another machine that has the Inbox dir and homedirs NFS import mounted from the production mailserver. I then have 5 people test it in this test environment.... A) Then I can deal with the index filesystem in one of two ways: 1) Make it local OR 2) NFS import it from the

Hi, I have lost a ZFS volume and I am hoping to get some help to recover the information ( a couple of months worth of work :( ). I have been using ZFS for more than 6 months on this project. Yesterday I ran a "zvol status" command, the system froze and rebooted. When it came back the discs where not available. See bellow the output of " zpool status", "format"

I''m looking for input on building an HA configuration for ZFS. I''ve read the FAQ and understand that the standard approach is to have a standby system with access to a shared pool that is imported during a failover. The problem is that we use ZFS for a specialized purpose that results in 10''s of thousands of filesystems (mostly snapshots and clones). All versions of

I have a backup system using zfs send/receive (I know there are pros and cons to that, but it''s suitable for what I need). What I have now is a script which runs daily, do zfs send, compress and write it to a file, then transfer it with ftp to a remote host. It does full backup every 1st, and do incremental (with 1st as reference) after that. It works, but not quite resource-effective
