One thing I do see with the issue we're having is that the files which have lost their permissions have "bad" versions on multiple bricks. Since the replica count is 2 for any given file, there should be only two copies of each, no? For example, the file below has zero-length, zero-permission versions on uds06/brick2 and uds-07/brick2, but good versions on uds-05/brick1 and uds-06/brick1. FILE is /09/38/1f/eastar/mail/entries/trash/2008-07-06T13_41_56-07_00.dump uds-05 -rw-r--r-- 2 apache apache 2233 Jul 6 2008 /export/brick1/vol1/09/38/1f/eastar/mail/entries/trash/2008-07-06T13_41_56-07_00.dump uds-06 -rw-r--r-- 2 apache apache 2233 Jul 6 2008 /export/brick1/vol1/09/38/1f/eastar/mail/entries/trash/2008-07-06T13_41_56-07_00.dump uds-06 ---------T 2 apache apache 0 Jul 23 03:11 /export/brick2/vol1/09/38/1f/eastar/mail/entries/trash/2008-07-06T13_41_56-07_00.dump uds-07 ---------T 2 apache apache 0 Jul 23 03:11 /export/brick2/vol1/09/38/1f/eastar/mail/entries/trash/2008-07-06T13_41_56-07_00.dump Is it acceptable for me to just delete the zero-length copies?
