...orm zfs receive - The receive performs correctly in around 3 to 3 1/2 minutes, and at the end of it, the state of the second host is identical to the state of the first host Now, when I perform the following steps: - Restore the state of the second host to the initial state (using zfs rollback -r snapshotname) - Run zfs receive for a second time on the second host Now the second host appears to lock up. I wait half an hour and the zfs receive command has not completed. I try to terminate the command with cntl-c and I get no response. But if I take the following action: - Open a second terminal windo...

...Really a bad choice apparently, since it seems impossible to delete them now: I cannot find how to enter the snapshot name properly due to the space. Quotes don't seem to help; escaping the space doesn't help either. Anybody knows how to solve this? eg: snapshot-delete DOMINO1-prealloc --snapshotname 'W2K3-virgin install' error: Domain snapshot not found: no snapshot with matching name ''W2K3-virgin' (-> notive also the extra ' added ) root at VLET3:~# time virsh snapshot-delete DOMINO1-prealloc "W2K3-virgin\ install" error: unexpected data 'install&...

...overlay, as e.g. inserts in a database - rsync the base file to a cifs server. With rsync not the complete, likely big file is transferred but just the delta - blockcommit the overlay: blockcommit guest /path/to/testsn --active --wait --verbose --pivot - delete the snapshot: snapshot-delete guest --snapshotname testsn --metadata - remove the overlay Is that ok ? How "safe" is blockcommit on a running guest ? It's possible that during the rsync, when the guest is running, some inserts are done in a database. Is it safe to copy the new sectors (i assume that's what blockcommit does) unde...

Hi folks, first post :) I'm running Redhat 6 x64 with ibvirt-0.10.2-18 and qemu-img-rhev-0.12.1.2-2.355 My question is, if I do something like the following..

...kvm 1.4.0 and libvirt 1.0.2. If a VM has multiple disks, I'd like to back them up individually with separate calls to snapshot-create-as, so I can more easily manage the disk images. The code I have now is essentially as follows: virsh snapshot-create-as --domain "vmname" --name "snapshotname" --description "snapshot description" --disk-only --atomic --no-metadata --diskspec "vda" I run this command for each block device (e.g vda, vdb, etc). However, after running the above command (to only backup vda), I see that a snapshot has also been created for vdb. I tr...

ZFS claims that it can recover user error such as accidentally deleting of files. How does it work? Does it only work for mirrored or RAID-Z pool? What is the command to perform the task? Also for COW, I understand that during the transaction (while data is been undated), ZFS keeps a copy of the previous data. However, once the transaction is successfully completed, isn''t it the case

I have a 1.5TB disk that has several partitions. One of them is 900GB. Now I can only see 300GB. Where is the rest? Is there a command I can do to reach the rest of the data? Will scrub help? -- This message posted from opensolaris.org
