Greetings. As mentioned previously, I may have ruined all thin volumes on a thin pool of mine due to the metadata overflow problem. I am running LVM version 2.02.98 on kernel 3.11.0-19-generic. I managed to compile LVM version 2.02.99 in order to get the metadata resize feature as described in the ChangeLog: "Add lvresize support for online thin pool metadata volume resize." I performed the metadata resize which seemed to work fine, but none of my thin volumes will activate. I would like to know whether the thin volumes are recoverable or not, but I have been unable to determine my next step. Here's what I have so far: jeremy@data-pool:~$ sudo lvdisplay ssmirrors/ThinPool --- Logical volume --- LV Name ThinPool VG Name ssmirrors LV UUID DzHi2N-Wle2-MpdN-9VEm-FeYw-pQI4-q6PKnd LV Write

What have you been doing here ? Have you used 'live' thin-pool metadata for resize ? (i.e. you were operating with active thin-pool volume, while using command thin_repair on _tmeta device ? You could eventually try to vgcfgbackup your VG, manually edit pool's transaction id to match kernel number, but you've been warned - that there were most probably 6 other transaction which are lost ? This may also mean - the changes in chunks are also lost - so if your volumes were allocating/releasing chunks - it's all lost (depending on what have you been doing - hard to guess...) You should be able to active pool with matching transaction_id, but it's somewhat unpredictable if all LVs will have the right content. (restore operation is going to be improved to add more validation) Zdenek _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
