I've gotten this problem about 4-5 times this past year where there is a bad 
directory entry in th ext3 file system that causes an aborted jornal causing 
a read-only file system. 

An hb_standby & hb_takeover fixes the problems. Whenever I do a chkdsk the 
filesystem has no errors, so it appears to be in memory (wasn't there 
another post on a similar issue?). 

Any inputs, suggestions, strategies to deal with the bug? 

Here are my log files:
Jan 17 01:01:19 nfs1 kernel: EXT3-fs error (device drbd0): ext3_readdir: bad 
entry in directory #1574044: rec_len %% 4 != 0 -
