Comments

[Andreas Dilger]

This is just a bad interaction between wide striping and ACLs both consuming the limited xattr space for ldiskfs/ext4. Not much that can be done about this for ldiskfs, except change the test to reduce the number of stripes on the files to a constant so the test is deterministic, or reduce the number of ACLs created based on the number of stripes on the file.

I would recommend to just create the file with "lfs setstripe -c 1" since the goal of this test is to verify there are no bugs in the ACL code, not on how many stripes are on the file.

We haven't seen this test fail in this way in the past year and a half. Let's close this ticket.

If we see this failure again, please open a new ticket.
