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? Thanks & Regards, sridhar. -- This message posted

Hi Peter, Should I assume that the virsh domfsfreeze, does not require the qemu-agent service in the guest? PS. I couldn't find the result.

Hi, The following patch series fixes hangup after creating checkpoint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux

Hi all. I'm having issues while creating snapshots. I posted on Stack Exchange [1], but figured I might get more success here. My VM backup script fails while creating the snapshot. virsh snapshot-create-as --domain machine_1 snap --diskspec vda,file=/srv/test/test-snap.qcow2 --disk-only --atomic --no-metadata --quiesce error: Requested operation is not valid: domain is

Hi, I was wondering if anyone would know if this is just an accounting-type error with the recorded "version=" stored on disk, or if there are/could-be any deeper issues with an "upgraded" zpool? I created a pool under a Sol10_x86_u3 install (11/06?), and zdb correctly reported the pool as a "version=3" pool. I reinstalled the OS with a u4 (08/07), ran zpool

Hi, since hostid is stored in the label, "zpool import" failed if the hostid dind''t match. Under certain circonstances (ldom failover) it means you have to manually force the zpool import while booting. With more than 80 LDOMs on a single host it will be great if we could configure the machine back to the old behavior where it didn''t failed, maybe with a /etc/sytem

I''m having following issue .. i import the zpool and it shows pool imported correctly but after few seconds when i issue command zpool list .. it does not show any pool and when again i try to import it says device is missing in pool .. what could be the reason for this .. and yes this all started after i upgraded the powerpath abcxxxx # zpool import pool: emcpool1 id:

Hello All, I''m transitioning data off my old UFS partitions onto ZFS. I don''t have a lot of duplicate space so I created a zpool, rsync''ed the data from UFS to the ZFS mount and then repartitioned the UFS drive to have partitions that match the cylinder count of the ZFS. The idea here is that once the data is over I wipe out UFS and then attach that partition to the

Hi, I was playing around with NexentaCP and its zfs boot facility. I tried to figure out how what commands to run and I ran zpool history like this # zpool history 2007-06-20.10:19:46 zfs snapshot syspool/rootfs at mysnapshot 2007-06-20.10:20:03 zfs clone syspool/rootfs at mysnapshot syspool/myrootfs 2007-06-20.10:23:21 zfs set bootfs=syspool/myrootfs syspool As you can see it says I did a

Hello, We had a situation at customer site where one of the zpool complains about missing devices. We do not know which devices are missing. Here are the details: Customer had a zpool created on a hardware raid(SAN). There is no redundancy in the pool. Pool had 13 LUN''s, customer wanted to increase the size of and added 5 more Luns. During zpool add process system paniced with zfs

Evening all, I''m new to Solaris but after drooling over zfs for ages I finally took the plunge. First off I had 2x1Tb hdd in raid1 XFS format using mdadm, so using a opensolaris vm image I transfered one side of the mirror to the other in zfs. (using rsync and it took 3days!) So with a 1 disk zpool carrying all my data I brought both the drives over in a new box, all going swimmingly

I noted this PSARC thread with interest: Re: zpool autoexpand property [PSARC/2008/353 Self Review] because it so happens that during a recent disk upgrade, on a laptop. I''ve migrated a zpool off of one partition onto a slightly larger one, and I''d like to somehow tell zfs to grow the zpool to fill the new partition. So, what''s the best way to do this? (and is it
