We are running ext3 with external journal on an ssd disk, as described on http://insights.oetiker.ch/linux/external-journal-on-ssd/ Today our server crashed (reason unknown) and when it booted again, all the ext3 filesystems with external journal refused to mount with the following error message Mar 3 12:16:58 srv-rhein kernel: [ 331.556972] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.605125] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.641793] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.668446] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.714423] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.749856] EXT3-fs: journal UUID does not match [kern.err] Mar 3 12:16:58 srv-rhein kernel: [ 331.779711] EXT3-fs: journal UUID does not match [kern.err] It was the same from ALL filesystems so I supect there is a systematic problem ... We are running kernel 2.6.22.18 The filesystems were all mounted with defaults,rw,errors=panic,noatime,data=journal I could recover from the problem by - fsck of the filesystems (all were consistant) - re-initializing all journals - re-adding all the journals Any ideas what caused the problem ? After all this is exactly the type of crash we have these journals for, so it is pretty bad when they fail exactly at that moment ... Should we not be using the LABEL syntax for journal reference ? cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch tobi@xxxxxxxxxx ++41 62 775 9902 / sb: -9900 _______________________________________________ Ext3-users mailing list Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
