Install went OK, and the FC LVM app shows the volume correctly, however I now can't mount it (despite all the devices existing as they should): # mount -t jfs /dev/mapper/MediaGroup-Media /Video mount: wrong fs type, bad option, bad superblock on /dev/mapper/MediaGroup-Media, missing codepage or other error In some cases useful info is found in syslog - try dmesg | tail or so The last line in dmesg is: JFS: nTxBlock = 8093, nTxLock = 64745 ...and /var/log/messages shows no oopsie either. Back at square one... Ben
