We are experiencing a serious problem with a 1TB filesystem under RH3 kernel 2.4.21-27 on a Bi-xeon DELL PE1750. The disks are HDS 9570V with Qlogic 2312 FC attach.
After slowdown due to excessive IOWAIT and enless ls commands in a 560000 inode directory (I know this may sound not reasonable!) ,
we have done a jfs_fsck who simply destroyed the directory to put it in lost+found.
We are currently restoring it from backups.
Do you think that a bug in JFS could be in cause?
The file system was created in jfs 1.1.2 and we are currently running jfs 1.1.10
Any hint would help.
