Hello to all the list' members I'm here writing because I've already seen the warning in subject, but with last word "thin", many LVs were inactive, no problem, in that case, installing the needed thin provisioning module, was fixing the issue, and the needed LVs got activated. But here I have a never seen before last word "thick", so WARNING: Unrecognized segment type thick so no way to activate an inactive LV. At the begin lvscan was returning both the warnings WARNING: Unrecognized segment type thin WARNING: Unrecognized segment type thick I've installed as usual the thin provisioning module and all but one the LVs got active... except but one ( needed one , obviously :-) ). So the situation is #lvscan WARNING: Unrecognized segment type thick and only one LV inactive, need to activate it So... what to do? Do you know about this? Looks like that logical volume can't be activated because of that thick warning. Also they are totally missing some VGs and LVs on this storage and so, thank you if you can link a safe procedure to try to restore a slightly corrupted LVM2. Is there any sort of fsck like procedure that could scan LVM2 metadata and try to pull out/restore as many VGs and LVs as possible? Thank you for any appreciated link Thank you in advance for any hint Cor _______________________________________________ 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/
