[ovirt-users] Re: Cannot acquire Lock .... snapshot error

Hi all, after update vdsm I run this command: *[root@infm-vm04 ~]# vdsm-tool -v check-volume-leases* *WARNING: Make sure there are no running storage operations.* *Do you want to check volume leases? [yes,NO] yes* *Checking active storage domains. This can take several minutes, please wait.* After that I saw some volumes with issue: *The following volume leases need repair:* *- domain: 47b7c9aa-ef53-48bc-bb55-4a1a0ba5c8d5* * - image: 4b2a6552-847c-43f4-a180-b037d0b93a30* * - volume: 6eb8caf0-b120-40e5-86b5-405f15d1245a* * - image: 871196b2-9d8b-422f-9a3e-be54e100dc5c* * - volume: 861ff7dd-a01c-47f7-8a01-95bc766c2607* * - image: 267b8b8c-da09-44ef-81b3-065dfa2e7085* * - volume: d5f3158a-87ac-4c02-84ba-fcb86b8688a0* * - image: c5611862-6504-445e-a6c8-f1e1a95b5df7* * - volume: e156ac2e-09ac-4e1e-a139-17fa374a96d4* * - image: e765c9c4-2ef9-4c8f-a573-8cd2b0a0a3a2* * - volume: 47d81cbe-598a-402a-9795-1d046c45b7b1* * - image: ab88a08c-910d-44dd-bdf8-8242001ba527* * - volume: 86c72239-525f-4b0b-9aa6-763fc71340bc* * - image: 5e8c4620-b6a5-4fc6-a5bb-f209173d186c* * - volume: 0f52831b-ec35-4140-9a8c-fa24c2647f17* * - image: a67809fc-b830-4ea3-af66-b5b9285b4924* * - volume: 26c6bdd7-1382-4e8e-addc-dcd3898b317f* *Do you want to repair the leases?
