[Gluster-users] Files losing permissions

[Justin Dossey]

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?
