Re: [Users] VM has paused due to unknown storage error

I managed to get the guest running again by using dd and q emu-img to export the filesystem image and base image , convert to raw format and run a fsck on the loop ed part ition. When mounted as a loop filesystem, fsck easily repaired it . Any ideas why oVirt kept pausing the guest and did no t allow fsck to repair the filesystem?

I cleared up space by removing old application logs within the guest, rebooted the g uest and was presented with the following information message during bootup when the filesystem ext3/ 4 scan runs: Clearing orhpaned inode ..... Shortly after this message the the guest is p aused by oVirt and the "VM has paused due to unknown storage error" message is displayed in the oVirt web GUI. On the physical node itself, I fo und t he following error in /var/log/vdsm/vd sm.log: libvirtEventLoop:: INFO::2012-12-02 09:05:50,296::libvirtvm::1965::vm.Vm::(_onAbnormalStop) vmId=`23b9212c-1e25-4003-aa18-b1e819bf6bb1`::abnormal vm stop device ide0-0-1 error eother Any ideas on how to get more inf ormation on what exactly the error is? I've tried booting the guest into r es cue mode , run a manual fsck on the logical v olume but each time the guest is automaticall paused due to the "unknown storage error". We are using a FC SAN for s torage , s o what I've decided to try is expo rt the disk using "dd" on the physical node and t hen try repairing it by mounting it as a loop filesystem on a nother physical ser ver , and then use "dd" to import it back in again. Is this the right approach to take to get the system back online? -- Get important Linux and industry-related news at: facebook.com/dcdata Kind regards, David Wilson CNS,CLS, LINUX+, CLA, DCTS, LPIC3 LinuxTech CC t/a DcData CK number: 2001/058368/23 Website: http://www.dcdata.co.za Support: +27(0)860-1-LINUX Mobile: +27(0)824147413 Tel: +27(0)333446100 Fax: +27(0)866878971 Time to evaluate your email security provider?
