Hi I put the journal on LVM over multipath for my OSTs
formating the OST was made with mkfs.lustre -v --reformat --fsname=datafs --ost --mgsnode=10.0.0.1 --mgsnode=10.0.0.2 --failover=10.0.0.3 --mkfsoptions="-E stride=64 -E stripe-width=9 -J device=LABEL=JNL_OST0_DATA -i 131072" /dev/mpath/ost0_data and now I'm fighting against udev since external journal device major and minor number seem to be hard coded in the file system and change on reboot [EMAIL PROTECTED] rules.d]# tune2fs -l /dev/mpath/ost0_data tune2fs 1.40.7.sun3 (28-Feb-2008) Filesystem volume name: datafs-OST0000 Last mounted on: <not available> Filesystem UUID: 7507ef98-4475-4612-a24b-fb7b0712ea42 [...] Journal UUID: 41f9f23d-b23b-4bec-b694-68bfca9d35c7 Journal device: 0xfd19 Default directory hash: tea Directory Hash Seed: b2550fed-3ffe-4f13-ab8e-a5de49ef9fec [EMAIL PROTECTED] rules.d]# ls -l /dev/mapper/JNL_SUMO1-jnl_ost0_data brw-rw---- 1 root disk 253, 23 Aug 19 14:15 /dev/mapper/JNL_SUMO1-jnl_ost0_data trying with tune2fs to change the device doesn't seem to work or i don't used the good syntax [EMAIL PROTECTED] rules.d]# tune2fs -J device=/dev/mapper/JNL_SUMO1-jnl_ost0_data /dev/mpath/ost0_data tune2fs 1.40.7.sun3 (28-Feb-2008) The filesystem already has a journal. what solution could you propose to recover my filesystem Thanks in advance -- Weill Philippe - Administrateur Systeme et Reseaux CNRS Service Aeronomie - Universite Pierre et Marie Curie - _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
