Hi,I have attached 2 pictures.On the fcerrorovirt,jpg, you can see this "status", on the other shows so on the storage is "everyting is ok". There are 4 volumes and the first one (50TB) is the "problem" storage. Thankscsabany-------- Eredeti levél --------Feladó: Strahil Nikolov via Users <users(a)ovirt.xn--org&gt;dtum-r7a: 2022 május 3 20:24:11Tárgy: [ovirt-users] Re: FC Storage recoverCímzett: csabany(a)freemail.hu users(a)ovirt.org&gt;I see the 4th FC ID, but it's on "Can't Extend" status.I have no idea what this one means. Can you give a screenshot ?Best Regards,Strahil NikolovHi,We have a 4 node cluster (4.4.10) and a standalone manager.We attached to this cluster 4 volumes on FC.Last week we lost the storage canisters (both), but recovered one of them from the storage disks. Unfortunatly only 3 storages came back from offline.I see the 4th FC ID, but it's on "Can't Extend" status.If i check the storages on nodes (lsblk), i can see only the ID not more on this 4th storage.Do you know any recovery tool or any idea for this situation?Thanks csabany    _______________________________________________Users mailing list -- users(a)ovirt.orgTo unsubscribe send an email to users-leave(a)ovirt.orgPrivacy Statement: https://www.ovirt.org/privacy-policy.htmloVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/MSTFARNGJ4S...

That was i tried first but i got "Error while executing action: Cannot deactivate Storage. The relevant Storage Domain's status is Inactive." message.Which logfile should i send from the SPM host? I downloded and zipped the whole /var/log but it's too large (105mb).Thankscsabany-------- Eredeti levél --------Feladó: Strahil Nikolov <hunter86_bg(a)yahoo.xn--com&gt;dtum-r7a: 2022 május 4 17:23:03Tárgy: Re: [ovirt-users] Re: FC Storage recoverCímzett: Nyika Csaba <csabany(a)freemail.hu&gt; users(a)ovirt.org <users(a)ovirt.org&gt;You will have to provide some logs from the SPM.If you don't use the storage domain (at least this is the impression), try to set it into maintenance and activate it again (UI -> Storage domain -> Select domain -> Datacenter -> Maintenance).Best Regards,Strahil NikolovOn Wed, May 4, 2022 at 18:00, Nyika Csaba&lt;csabany(a)freemail.hu&gt; wrote:_______________________________________________Users mailing list -- users(a)ovirt.orgTo unsubscribe send an email to users-leave(a)ovirt.orgPrivacy Statement: https://www.ovirt.org/privacy-policy.htmloVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/XAHLBEVJTUU...

Do all hosts have 'active ready running' ? P.S.: It will take me some time to look in the logs as it's hard to check them on the move.

According to vdsm, there are some failed multipath paths -> you will need to clear them (pure LinuxSystem Administration) as they might cause the real symptom. According to the log there are read errors. You have to figure out why vdsm fails to read the LUN.Can you try to 'dd if=/dev/mapper/multipath-wwid of=/dev/null bs=10M count=200' and see if it errors out.
