Hi, I have two questions: 1) Is there any way of renaming zpool without export/import ?? 2) If I took hardware snapshot of devices under a zpool ( where the snapshot device will be exact copy including metadata i.e zpool and associated file systems) is there any way to rename zpool name of snapshotted devices ?? without losing data part?

I am getting the following error, however as you can see below this is a SMI label... cannot set property for ''rpool'': property ''bootfs'' not supported on EFI labeled devices # zpool get bootfs rpool NAME PROPERTY VALUE SOURCE rpool bootfs - default # zpool set bootfs=rpool/ROOT/s10s_u8wos_08a rpool cannot set property for ''rpool'': property

We have a zpool made of 4 512g iscsi luns located on a network appliance. We are seeing poor read performance from the zfs pool. The release of solaris we are using is: Solaris 10 10/09 s10s_u8wos_08a SPARC The server itself is a T2000 I was wondering how we can tell if the zfs_vdev_max_pending setting is impeding read performance of the zfs pool? (The pool consists of lots of small files).

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP. Here is the error message when I try to create my pool: bash-3.00# zpool create tank /dev/dsk/vpath1a warning: device in use checking failed: No such device internal error: unexpected error 22 at line 446 of ../common/libzfs_pool.c bash-3.00# zpool create tank /dev/dsk/vpath1c cannot open

I saw in another post that a best practices doc will be coming, but I figured I would try to get this working. I''m trying to understand why zfs uses so many "zfs create" so I can use it better. What makes sense is that each zfs fs can have it''s own options (compression, nfs, atime, quota, etc). I really love this because it is so tuneable -- compression on these

Hello all Samba enthusiasts. I am a noob w.r.t. samba configuration and just happened to use it on Solaris systems by creating conf files using copy-paste :-). This is just to convey that I'm no advanced user and might need help with the solutions / alternatives to come. Some background => Here is my smb.conf: === [global] workgroup = <company domain> server string = Samba

I am having compile problems with Dovecot v2.0.2 on a well patched Solaris 10u8 Sparc system using the included gcc compiler. Version 2.0.0 compiled with out any issues using the same configure syntax. My ./configure syntax looks like this: ./configure --with-ssl=openssl --with-shadow Yahoo and Google searches turned up nothing for me. Reviewing the file mountpoint.c between version 2.0.0

In v1.0 .. v1.1 deliver was writing incoming >128k mail to /tmp file (to avoid reading it all into memory). In v1.2 I moved it to user's home directory. This slowed deliveries for NFS users. Also people with filesystem quota had trouble since now user required twice as much available quota to save a message. The FS quota problem was "solved" by having quota-fs plugin change the

Hello, Is there a way to upgrade my current ZFS version. I show the version could be as high as 22. I tried the command below. It seems that you can only upgrade by upgrade the OS release.

Hi all, we have just bought a sun X2200M2 (4GB / 2 opteron 2214 / 2 disks 250GB SATA2, solaris 10 update 4) and a sun STK 2540 FC array (8 disks SAS 146 GB, 1 raid controller). The server is attached to the array with a single 4 Gb Fibre Channel link. I want to make a mirror using ZFS with this array. I have created 2 volumes on the array in RAID0 (stripe of 128 KB) presented to the host

I''ve got my first server deployment with ZFS. Consolidating a pair of other file servers that used to have a dozen or so NFS exports in /etc/dfs/dfstab similar to; /export/solaris/images /export/tools /export/ws ..... and so on.... For the new server, I have one large zfs pool; -bash-3.00# df -hl bigpool 16T 1.5T 15T 10% /export that I am starting to

Hello, I am trying to update files on LDOM boot disk from Control Domain, but I can''t get it working fully. I have a setup that allows to quickly deploy LDOM guest domains. The Golden OS Image of guest domain boot disk is on a ZFS Volume. This ZFS Volume has been Snapshot and Cloned for the quick deployment of guest domains. Filesystem in both the control domain and guest domain is

Anyone know of a SATA and/or SAS HBA with battery backed write cache? Seems like using a full-blown RAID controller and exporting each individual drive back to ZFS as a single LUN is a waste of power and $$$. Looking for any thoughts or ideas. Thanks. -Matt -- This message posted from opensolaris.org

Do we have enormous fragmentation here on our X4500 with Solaris 10, ZFS Version 10? What except zfs send/receive can be done to free the fragmented space? One ZFS was used for some month to store some large disk images (each 50GByte large) which are copied there with rsync. This ZFS then reports 6.39TByte usage with zfs list and only 2TByte usage with du. The other ZFS was used for similar

I believe ZFS is causing a panic whenever I attempt to mount an iso image (SXCR build 39) that happens to reside on a ZFS file system. The problem is 100% reproducible. I''m quite new to OpenSolaris, so I may be incorrect in saying it''s ZFS'' fault. Also, let me know if you need any additional information or debug output to help diagnose things.
