Hi Maor, I already added logs in my previous email, did you received them? I'm sending them again, but only privately to you not to burden the mailing list (or let me know if you prefer otherwise).

The behavior you mentioned, that suddenly the disk has disappeared from the setup, sounds very weird and I would like to investigate this a bit more. if you can please add the engine and vdsm logs, I can know what made the disk get removed from the setup, at the first place. Could it be that some one accessed the data base by any chance? Regarding the disk registration, basically it should not create any problems unless, if your disk was deleted manually form the DB, and there are still leftovers related to the disk in some of the tables. Once the disk is registered to the setup, you can try to attach it to the VM, and try to run it. Regards, Maor ----- Original Message -----

I'm waiting for any comments on the two OVF disk or any advice before proceeding with the registering command (test in production environment hmmmmm)

Thank you for your reply! I'm unsure if the disk contained any snapshots. I do not think so. Is the register action a safe one to do in production system? I wouldn't mess any of my existing running servers.
Here the relevant logs from the date ./engine.log-20150501.gz:2015-04-29 16:10:40,868 : disk creation ("hertz_disk5" newImageId = 4ab070c0-fb16-452d-8521-4ff0b004aef3) ./engine.log-20150512.gz:2015-05-04 17:22:42,691 : last occurrence of the imageid
Please note from ./engine.log-20150512.gz 2015-05-11 12:07:16,719 : creation of two disk OVF store (??) on the same storage domain 7a48fe46-2112-40a4-814f-24d74c760b2d right after the volume expansion
In the instructions.txt what I did to enlarge the volume (and lose the disk) (the guides is informational only, I followed the steps on a different server)
Here some cats to thank you in advance https://www.youtube.com/watch?v=nfTY41-zC7Y
lol :) Nice cats

Hi Andrea,
First of all, the issue sounds quite severe, can u please attach the engine logs so we can try to figure out how that happened. second, does this disk contained any snapshots? If not, can you try to register it back (see http://www.ovirt.org/Features/ImportStorageDomain#Register_an_unregist ered_disk)
Regards, Maor

Ok, so,
After _ a lot _ of unsuccessful approach, I finally connected to postegre DB directly.
Browsing the tables I found “unregistered_ovf_of_entities” where there is a reference of the missing disk
@ovf:diskId:4ab070c0-fb16-452d-8521-4ff0b004aef3
@ovf:size:210
@ovf:actual_size:210
@ovf:vm_snapshot_id:2e24b255-bb84-4284-8785-e2a042045882

@ovf:format: http://www.vmware.com/specifications/vmdk.html#sparse
@ovf:volume-format:RAW
@ovf:volume-type:Preallocated
@ovf:disk-interface:VirtIO
@ovf:boot:false
@ovf:disk-alias:hertz_disk5
@ovf:disk-description:disk for SYBASE installation, on SAN shared storage
@ovf:wipe-after-delete:false
However, I’ve been unable to find any other helpful details.
I guess the disk is not recoverable at this point?
Any guru who has a good ovirt DB kwnoledge willing to give me some advice?
Thanks as usual
AG

Hi gentlemen,
I recently found an error on 1 of my storages: it was complaining about no free space but the VM was running and disk operational.
Since I needed to perform some maintenance on the VM, I shut it down and at restart VM couldn’t boot up properly.
Checked VM via console and a disk was missing. Edited fstab (luckily this disk was not root but heck! It had a Sybase DB on it!) and restarted VM this time ok.
Since the disk resides on the dstore with no space, I expanded the iSCSI LUN, then refreshed multipath on hosts, then resized PVs and now ovirt is showing the correct size (logs do not complain anymore on no free space).
BUUUT
Now disk is missing. It is not shown anymore on Disks tab nor anywhere else.
Problem is that storage shows 214GB occupancy (size of the missing disk) so data is there but cannot find it anymore.
Logs show original disk creation, errors from the lack of space, refresh of the storage size and then.... no more references on the disk.
What can I do to find those missing ~210GBs?
Cheers
Andrea Ghelardi
