Subject: Issue: errno:28 (No space left on device)
Date: Tue, 9 Aug 2016 13:50:04 +0200 [thread overview]
Message-ID: <e4671ca6-38bc-ce32-0bc9-c1e7bc9873cd@web.de> (raw)
Hello!
I'm facing a severe issue with Debian installation using BTRFS:
errno:28 (No space left on device)
After a few minutes of system usage I get this error message for any
action, means there's really no disk space left.
However, the output of btrfs fi usage / reports that ~10% of disk space
should be free.
I have 2 questions:
1. Why is the OS reporting an error "Issue: errno:28 (No space left on
device)" whereas "btrfs fi usage" reports free space?
2. How can I solve this issue w/o the possibility of extending the
partition?
THX
