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

Hi, I am posting my question to both storage-discuss and zfs-discuss as I am not quite sure what is causing the messages I am receiving. I have recently migrated my zfs volume from b104 to b134 and upgraded it from zfs version 14 to 22. It consist of two zvol''s ''vol01/zvol01'' and ''vol01/zvol02''. During zpool import I am getting a non-zero exit code,

Hey all, I''m setting up a ZFS based fileserver to use both as a shared network drive and separately to have an iSCSI target to be used as the "Hard disk" of a windows based VM runninf on another machine. I''ve built the machine, installed the OS, created the RAIDZ pool and now have a couple of questions (I''m pretty much new to Solaris by the way but have been

I''ve recently upgraded my x4500 to Nevada build 97, and am having problems with the iscsi target. Background: this box is used to serve NFS underlying a VMware ESX environment (zfs filesystem-type datasets) and presents iSCSI targets (zfs zvol datasets) for a Windows host and to act as zoneroots for Solaris 10 hosts. For optimal random-read performance, I''ve configured a single

We''re using some X4540s, with OpenSolaris 2008.11. According to my testing, to optimize our systems for our specific workload, I''ve determined that we get the best performance with the write cache disabled on every disk, and with zfs:zfs_nocacheflush=1 set in /etc/system. The only issue is setting the write cache permanently, or at least quickly. Right now, as it is,

Good evening, Eli. 2012/3/25 Bendersky, Eli <eli.bendersky at intel.com>: > It appears that some of the bots on http://bb.pgr.jp use a really old > version of Python (2.4) I know. It is extremely old. IIRC, RHEL5(and its clone) does not provide python greater than 2.4 by default. EPEL (extra packages for enterprise linux, by fedora) provides 2.6. CentOS5, my buildslave, and RHEL5 can

Hi, In migrating from **VM to ZFS am I going to have an issue with Major/Minor numbers with NFS mounts? Take the following scenario. 1. NFS clients are connected to an active NFS server that has SAN shared storage between the active and standby nodes in a cluster. 2. The NFS clients are using the major/minor numbers on the active node in the cluster to communicate to the NFS active server. 3.

(i use the term loosely because i know that zfs likes whole volumes better) when installing ubuntu, i got in the habit of using a separate partition for my home directory so that my data and gnome settings would all remain intact when i reinstalled or upgraded. i''m running osol 2008.11 on an ultra 20, which has only two drives. i''ve got all my data located in my home directory,

Hi. I thought I''d take a stab at the first steps of porting ZFS to Darwin. I realize there are rumors that Apple is already doing this, but my contact at Apple has yet to get back to me to verify this. In the meantime, I wanted to see how hard it would be. I started with libzfs, and promptly ran into issues with libnvpair. It wants sys/nvpair.h, but I can''t find that in the

Hello ZFS experts: I would like to study ZFS de-duplication feature. Can someone please let me know which directory/files I should be looking at? Thanks in advance. -- This message posted from opensolaris.org

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

Hi all, Is there some documentation or some example on how to interpret the arg0 .. arg<n> for the aioread, aiowrite, aiowait syscalls? The system call name for all three seems to be "kaio".

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")

Hello. I have a Solaris 11/11 x86 box (which I migrated from SolEx 11/10 a couple of weeks ago). Without no obvious reason (at least for me), after an uptime of 1 to 2 days (observed 3 times now) Solaris sets arc_no_grow to 1 and then never sets it back to 0. ARC is being shrunk to less than 1 GB -- needless to say that performance is terrible. There is not much load on this system. Memory
