2 clues: -the original size of the disk was 750G and was extended a month ago to 1100G. The System rebooted fine several times, and took the new size with no problems. -I run fdisk from a centos 7 rescue cd and '/dev/vda' reported 750G. then, I took a snapshot of the disk to play with recovery tools and now fdisk reports 1100G... ¬¬ so my guess is on the extend and later migration to a different storage domain caused the issue. Im currently running testdisk to see if theres any partition to recover. regards, 2018-05-13 12:31 GMT-03:00 Juan Pablo <pablo.localhost(a)gmail.com&gt;: > I removed the auto-snapshot and still no lucky. no bootable disk found. =( > ideas? > > > 2018-05-13 12:26 GMT-03:00 Juan Pablo <pablo.localhost(a)gmail.com&gt;: > >> benny, thanks for your reply: >> ok, so the steps are : removing the snapshot on the first place. then >> what do you suggest? >> >> >> 2018-05-12 15:23 GMT-03:00 Nir Soffer <nsoffer(a)redhat.com&gt;: >> >>> On Sat, 12 May 2018, 11:32 Benny Zlotnik, <bzlotnik(a)redhat.com&gt; wrote: >>> >>>> Using the auto-generated snapshot is generally a bad idea as it's >>>> inconsistent, >>>> >>> >>> What do you mean by inconsistant? >>> >>> >>> you should remove it before moving further >>>> >>>> On Fri, May 11, 2018 at 7:25 PM, Juan Pablo <pablo.localhost(a)gmail.com >>>> > wrote: >>>> >>>>> I rebooted it with no luck, them I used the auto-gen snapshot , same >>>>> luck. >>>>> attaching the logs in gdrive >>>>> >>>>> thanks in advance >>>>> >>>>> 2018-05-11 12:50 GMT-03:00 Benny Zlotnik <bzlotnik(a)redhat.com&gt;: >>>>> >>>>>> I see here a failed attempt: >>>>>> 2018-05-09 16:00:20,129-03 ERROR [org.ovirt.engine.core.dal.dbb >>>>>> roker.auditloghandling.AuditLogDirector] >>>>>> (EE-ManagedThreadFactory-engineScheduled-Thread-67) >>>>>> [bd8eeb1d-f49a-4f91-a521-e0f31b4a7cbd] EVENT_ID: >>>>>> USER_MOVED_DISK_FINISHED_FAILURE(2,011), User admin@internal-authz >>>>>> have failed to move disk mail02-int_Disk1 to domain 2penLA. >>>>>> >>>>>> Then another: >>>>>> 2018-05-09 16:15:06,998-03 ERROR [org.ovirt.engine.core.dal.dbb >>>>>> roker.auditloghandling.AuditLogDirector] >>>>>> (EE-ManagedThreadFactory-engineScheduled-Thread-34) [] EVENT_ID: >>>>>> USER_MOVED_DISK_FINISHED_FAILURE(2,011), User admin@internal-authz >>>>>> have failed to move disk mail02-int_Disk1 to domain 2penLA. >>>>>> >>>>>> Here I see a successful attempt: >>>>>> 2018-05-09 21:58:42,628-03 INFO [org.ovirt.engine.core.dal.dbb >>>>>> roker.auditloghandling.AuditLogDirector] (default task-50) >>>>>> [940b051c-8c63-4711-baf9-f3520bb2b825] EVENT_ID: >>>>>> USER_MOVED_DISK(2,008), User admin@internal-authz moving disk >>>>>> mail02-int_Disk1 to domain 2penLA. >>>>>> >>>>>> >>>>>> Then, in the last attempt I see the attempt was successful but live >>>>>> merge failed: >>>>>> 2018-05-11 03:37:59,509-03 ERROR [org.ovirt.engine.core.bll.MergeStatusCommand] >>>>>> (EE-ManagedThreadFactory-commandCoordinator-Thread-2) >>>>>> [d5b7fdf5-9c37-4c1f-8543-a7bc75c993a5] Failed to live merge, still >>>>>> in volume chain: [5d9d2958-96bc-49fa-9100-2f33a3ba737f, >>>>>> 52532d05-970e-4643-9774-96c31796062c] >>>>>> 2018-05-11 03:38:01,495-03 INFO [org.ovirt.engine.core.bll.Ser >>>>>> ialChildCommandsExecutionCallback] (EE-ManagedThreadFactory-engineScheduled-Thread-51) >>>>>> [d5b7fdf5-9c37-4c1f-8543-a7bc75c993a5] Command 'LiveMigrateDisk' >>>>>> (id: '115fc375-6018-4d59-b9f2-51ee05ca49f8') waiting on child >>>>>> command id: '26bc52a4-4509-4577-b342-44a679bc628f' >>>>>> type:'RemoveSnapshot' to complete >>>>>> 2018-05-11 03:38:01,501-03 ERROR [org.ovirt.engine.core.bll.sna >>>>>> pshots.RemoveSnapshotSingleDiskLiveCommand] >>>>>> (EE-ManagedThreadFactory-engineScheduled-Thread-51) >>>>>> [d5b7fdf5-9c37-4c1f-8543-a7bc75c993a5] Command id: >>>>>> '4936d196-a891-4484-9cf5-fceaafbf3364 failed child command status >>>>>> for step 'MERGE_STATUS' >>>>>> 2018-05-11 03:38:01,501-03 INFO [org.ovirt.engine.core.bll.sna >>>>>> pshots.RemoveSnapshotSingleDiskLiveCommandCallback] >>>>>> (EE-ManagedThreadFactory-engineScheduled-Thread-51) >>>>>> [d5b7fdf5-9c37-4c1f-8543-a7bc75c993a5] Command >>>>>> 'RemoveSnapshotSingleDiskLive' id: '4936d196-a891-4484-9cf5-fceaafbf3364' >>>>>> child commands '[8da5f261-7edd-4930-8d9d-d34f232d84b3, >>>>>> 1c320f4b-7296-43c4-a3e6-8a868e23fc35, a0e9e70c-cd65-4dfb-bd00-076c4e99556a]' >>>>>> executions were completed, status 'FAILED' >>>>>> 2018-05-11 03:38:02,513-03 ERROR [org.ovirt.engine.core.bll.sna >>>>>> pshots.RemoveSnapshotSingleDiskLiveCommand] >>>>>> (EE-ManagedThreadFactory-engineScheduled-Thread-2) >>>>>> [d5b7fdf5-9c37-4c1f-8543-a7bc75c993a5] Merging of snapshot >>>>>> '319e8bbb-9efe-4de4-a9a6-862e3deb891f' images >>>>>> '52532d05-970e-4643-9774-96c31796062c'..'5d9d2958-96bc-49fa-9100-2f33a3ba737f' >>>>>> failed.

If the base is raw, the size seen by the guest is the size of the image. The snapshot is qcow2, the size seen by the guest is the size saved in the qcow2 header. Can you share the output of: qemu-img info --backing-chain /path/to/snapshot And: qemu-img info --backing-chain /path/to/base You can see the path in the vm xml, either in vdsm.log, or using virsh: virsh -r list virtsh -r dumpxml vm-id Nir > > regards, > > > 2018-05-13 15:25 GMT-03:00 Juan Pablo <pablo.localhost(a)gmail.com&gt;: > >> 2 clues: >> -the original size of the disk was 750G and was extended a month ago to >> 1100G.

Im still wondering why Ovirt moved an image and left it with errors, but reported the move as successful in the GUI. If you think it's related to the snapshot, its really strange as it's the first time I see this odd behavior, never got an issue like this when moving images+snaps. on the other side, if it moved the 700G image(and not the extra 400), why it's unconsistant? shouldn't be old, but nevertheless in good shape? is there anything else to try? thanks in advance! regards, 2018-05-14 12:01 GMT-03:00 Juan Pablo <pablo.localhost(a)gmail.com&gt;: > Hi Nir, thanks for the reply, here's the output: > > *(BASE)* > *[root@node02 ~]# * qemu-img info --backing-chain > /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/52532d0 > 5-970e-4643-9774-96c31796062c > image: /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/52532d0 > 5-970e-4643-9774-96c31796062c > file format: raw > virtual size: 700G (751619276800 bytes) > disk size: 0 > > > > *(with Snapshot)[root@node02 ~]# * qemu-img info --backing-chain > /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/86a6fdb > 9-b9a4-4b78-8e3d-940f83cedc5a > image: /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/86a6fdb > 9-b9a4-4b78-8e3d-940f83cedc5a > file format: qcow2 > virtual size: 1.1T (1181116006400 bytes) > disk size: 0 > cluster_size: 65536 > backing file: 52532d05-970e-4643-9774-96c31796062c (actual path: > /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/52532d0 > 5-970e-4643-9774-96c31796062c) > backing file format: raw > Format specific information: > compat: 1.1 > lazy refcounts: false > refcount bits: 16 > corrupt: false > > image: /rhev/data-center/mnt/blockSD/cec63cf0-9311-488d-b1fa-99c440 > 5e8379/images/65ec515e-0aae-4fe6-a561-387929c7fb4d/52532d0 > 5-970e-4643-9774-96c31796062c > file format: raw > virtual size: 700G (751619276800 bytes) > disk size: 0 > > I really appreciate your time helping, > regards, > > > 2018-05-14 11:36 GMT-03:00 Nir Soffer <nsoffer(a)redhat.com&gt;: > >> On Mon, May 14, 2018 at 5:19 PM Juan Pablo <pablo.localhost(a)gmail.com&gt; >> wrote: >> >>> ok, so Im confirming that the image is wrong somehow: >>> with no snapshot, from inside the vm disk size is reporting 750G. >>> with a snapshot, from inside the vm disk size is reporting 1100G. >>> both have no partitions on it, so I guess ovirt migrated the structure >>> of the 750G disk on a 1100 disk, any ideas to troubleshoot this and see if >>> there's data to recover? >>> >> >> Maybe you resized the disk after making a snapshot? >> >> If the base is raw, the size seen by the guest is the size of the image. >> >> The snapshot is qcow2, the size seen by the guest is the size saved in >> the qcow2 header. >> >> Can you share the output of: >> >> qemu-img info --backing-chain /path/to/snapshot >> >> And: >> >> qemu-img info --backing-chain /path/to/base >> >> You can see the path in the vm xml, either in vdsm.log, or using virsh: >> >> virsh -r list >> virtsh -r dumpxml vm-id >> >> Nir >> >> >>> >>> regards, >>> >>> >>> 2018-05-13 15:25 GMT-03:00 Juan Pablo <pablo.localhost(a)gmail.com&gt;: >>> >>>> 2 clues: >>>> -the original size of the disk was 750G and was extended a month ago >>>> to 1100G.
