I was able to regain access to the LV by renaming it, then renaming it back... [root@host1 ~]# lvrename /dev/array1/LVpics /dev/array1/LVpicsnew Renamed "LVpics" to "LVpicsnew" in volume group "array1" [root@host1 ~]# lvrename /dev/array1/LVpicsnew /dev/array1/LVpics Renamed "LVpicsnew" to "LVpics" in volume group "array1" There are 29 LVs in the VG and 25 of them came up OK and 4 had this problem. Note that there is only one single PV (a RAID6 array) in the VG, and there are two VGs on the machine. Is this expected behaviour, or is it something I should be worried about? --- Logical volume --- LV Path /dev/array1/LVpics LV Name LVpics VG Name array1 LV UUID WH7g9u-Ls7J-fIpQ-Hk2p-mUuH-QRKf-9uxcM2 LV Write Access read/write LV Creation host, time example.com, 2013-11-26 07:29:51 +1100 LV Status available # open 0 LV Size 350.00 GiB Current LE 89600 Segments 2 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:9 I am running Fedora 19 with kernel 3.11.9-200.fc19.x86_64 Thanks GC
