Hello my dear upstream heroes, We are using progs v4.4.1 and kernel 4.4.5 in Rockstor and sometimes this warning is displayed while assigning a qgroup. Here's a sample output. /sbin/btrfs qgroup assign 0/408 2015/6 /mnt2/<btrfs_pool> WARNING: quotas may be inconsistent, rescan needed 2015/6 is the qgroup of a subvolume(/mnt2/<btrfs_name>/<subvol_name>) created much earlier. This started happening since progs v4.2. There are three scenarios I've tested. 1. Just ignore the warning and check if the qgroup assignment succeeded with a "qgroup show" command. In most cases, the assignment shows up immediately. But it could take a bit in some cases. Is there any self/auto consistency check that is triggered by default? If so can someone explain how that works? 2. Add a --rescan option to to the "qgroup assign" command above to auto schedule a rescan as per the man page. Is this safe to do? What are pros and cons? 3. Execute a "quata rescan" separately if the warning is displayed. Is this any different from (2)?
