After adding a network to the file system and adding the IP for the failover node to the MDS it wouldn't mount. (I later found that --param failnode= is no longer valid - much to my chagrin) I attempted to run fsck against the file system but it responded that the e2fsprogs was out of date for the file system so I ran fsck.ldiskfs. The fsck.ldiskfs found some bad inodes and corrected them but on a subsequent run with the -n option (done to make sure it was clean) I started seeing a flood of "dirdata length set incorrectly" messages. I stopped it and was able to mount the FS but later the FS spontaneously unmounted.

What does this mean? Fortunately this file system is in pre-production and can be recreated (which is intended) but I'd like to know if this was caused by running fsck.ldiskfs since I did not see these messages on the first pass. The version of e2fsprogs (non-Redhat) is ldiskfsprogs-1.41.90.3chaos.wc3-0.ch5.x86_64. I have downloaded the wc4 version from the WC repo and installed it into a test image where I have rebooted the node into. I was able to use e2fsck to check the FS and I am using -fDy options but the "dirdata length set incorrectly" message continues to stream and has been going for more that an hour.

Any help would be appreciated.
