Hi everyone,we have 24TB SW-RAID6 array with one large JFS partition. There was power failure (bad UPS) when jfs_fsck have been running and after this accident I'm not able to get JFS clean.
There is jfs_fsck error which I get :
**Phase 1 - Check Blocks, Files/Directories, and Directory EntriesDuplicate reference to 4 block(s) beginning at offset 5975789204 found in file system object IA16.
Inode A16 has references to cross linked blocks.Multiple metadata references to 4 blocks beginning at offset 5975789204 have been detected.
Duplicate block references have been detected in Metadata. CANNOT CONTINUE.processing terminated: 10/25/2013 9:14:15 with return code: 10060 exit code: 4.
I'm able to mount partition read only and backup almost all data. Some data are unreadable, with jfs_lookup kernel error:
Oct 3 12:08:44 nash kernel: ERROR: (device md3): diRead: i_ino != di_number Oct 3 12:08:44 nash kernel: jfs_lookup: iget failed on inum 54550587 Oct 3 12:08:44 nash kernel: jfs_lookup: iget failed on inum 52483751 Oct 3 12:08:44 nash kernel: jfs_lookup: iget failed on inum 52483751One solution is reformat partition and restore data from backup, but with 23TB of data it is little bit time consuming. So I would like to try to use jfs_debugfs in some way and to repair existing partition. But I'm not sure how and if it's possible at all.
Can any JFS expert help me, please? Thanks in advance, Daniel Vecerka CTU Prague
