Hi all, Starting today I have an interesting problem: I deleted some files as part (old fcrontabs), which now persistently causes btrfs-send to fail. The error message I get is:
Aug 12 23:32:24 thetick make_backups.sh[1059]: ERROR: send ioctl failed with
-2: No such file or directory
Aug 12 23:32:25 thetick make_backups.sh[1059]: ERROR: unexpected EOF in stream.
There is nothing in the dmesg output.
Since this is the root file system, I haven't gotten a copy of the actual output
of "btrfs check", though I have run it from an initramfs rescue shell. The
output I saw there was much like the following (taken from an Email by Roman
Mamedov from 2014-12-28):
root 22730 inode 6236418 errors 2000, link count wrong unresolved ref dir
105512 index 586340 namelen 48 name [redacted].dat.bak filetype 0 errors 3, no
dir item, no dir index
Only in my case, it's "root 5" and "root 4" (I think), and the file names
(and other file system specifics) are of course different. I definitely saw
"errors 2000" (I take it that's supposed to be an error code?).
Is this something that "btrfs check --repair" (or something else) can safely
fix?
