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:fileRef:16736ce0-a9df-410f-9f29-3a28364cdd41/4ab070c0-fb16-452d-8521-4ff0b004aef3

    @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

Subject: missing disk after storage domain expansion

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
