We have bug, that looks like this.
After coping of a file with 'cp' to another location in the same fs some empty gaps happened.
Comparing the good to the bad file, the bad file has a 4096-byte segment of zeros at block offset 6799 of the file, and the last portion of the file (following the last even 1MB multiple) is also zeros. Looking at the bad file's OST object (stripe count is 1), the zero'd regions of the file are holes - no blocks allocated for those portions. The block allocations for the bad file go from 0-6798, block 6799 is missing, then 6800-8703, blocks 8704-8745 are missing. (8704 blocks is 34*1048576; the bad file ends at the last even 1MB boundary).
The bad file is missing block 6799, and blocks 8704-8745

[ I'm not sure if this is the best place to bring this up, but I'm currently unable to check out any Lustre source from Whamcloud.

FX: git clone -b master http://git.whamcloud.com/fs/lustre-release.git lustre-master Gives me: error: The requested URL returned error: 403 while accessing http://git.whamcloud.com/fs/lustre-release.git/info/refs And the same message attempting to use the Gerrit-provided git links for these patches. ] |
