Hello List, I am using lvm2-2.02.180 on SLES12SP4, I cannot remove the snap LV of root volume, which is based on multipath disk PV. e.g. linux-kkay:/ # lvremove /dev/system/snap_root WARNING: Reading VG system from disk because lvmetad metadata is invalid. Do you really want to remove active logical volume system/snap_root? [y/n]: y device-mapper: reload ioctl on (254:3) failed: Invalid argument Failed to refresh root without snapshot. But, I can remove the snap LV of data volume successfully, e.g. linux-kkay:/ # lvremove /dev/system/data_snap WARNING: Reading VG system from disk because lvmetad metadata is invalid. Do you really want to remove active logical volume system/data_snap? [y/n]: y Logical volume "data_snap" successfully removed If I use the ordinary disk as PV (rather than multipath disk), I cannot encounter this problem (both snap LVs can be removed).
Hi Please open new BZ case and provide full -vvvv traces of failing command and also possibly attache 'dmsetup table' 'dmsetup ls --tree' and 'dmsetup info -c' 'dmsetup status' Regards Zdenek _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
