...s stress tests. My current exercise involves writing to files using a shared-writable mmap() from two nodes. (Each node mmaps and writes to different files; I am not trying to access the same file from multiple nodes.) Both nodes are logging messages like these: [94355.116255] (ocfs2_wq,5995,6):ocfs2_block_check_validate:443 ERROR: CRC32 failed: stored: 2715161149, computed 575704001. Applying ECC.

...g. I then used tunefs to add discontig-bg, inline-data and indexed-dirs. During indexed-dirs tunefs segfaulted and since then, fsck didn't work anymore. I managed to mount the partition again but after some errors like the following Jan 11 23:11:56 www1 kernel: [ 2339.642683] (mc,3305,0):ocfs2_block_check_validate:443 ERROR: CRC32 failed: stored: 0x76176db1, computed 0x9e4c2434.
