# This testcase tests the 'ceph fs subvolume snapshot rm' when the osd is full.
|
|
# The snapshot rm fails with 'MetadataMgrException: -28 (error in write)' and
|
|
# truncates the config file of corresponding subvolume. Hence the subsequent
|
|
# snapshot rm of the same snapshot fails with 'MetadataMgrException: -2 (section 'GLOBAL' does not exist)'
|
|
# traceback.
|
|
|
|
# The osd is of the size 2GiB. The subvolume is created and 1.6GB file is written.
|
|
# Then full-ratios are set below 1GiB such that the osd is treated as full.
|
|
# The subvolume snapshot is taken which succeeds as no extra space is required
|
|
# for snapshot. Now, the removal of the snapshot fails with ENOSPACE as it
|
|
# fails to remove the snapshot metadata set. The snapshot removal fails
|
|
# but should not traceback and truncate the config file.
