Problems
1) btrfs check --repair _still_ takes all 32GB of RAM and crashes the
server, despite my deleting lots of snapshots.
Is it because I have too many files then?
Yes. Original check first gather all infomation about extent tree and
your files in RAM, then process one by one.
But deleting still counts, it does speed lowmem check up.
Understood.
2) I tried Su's master git branch for btrfs-progs to try and see how
Oh..No... My master branch is still 4.14. The true mater branch is
David's here:
https://github.com/kdave/btrfs-progs
But the master branch has a known bug which I fixed yesterday, please see
the mail.
So, if I git sync it now, it should have your fix, and I can run it,
correct?
Yes, please.
Ok, I am now running
gargamel:~# time btrfs check --mode=lowmem --repair /dev/mapper/dshelf2
using git master from https://github.com/kdave/btrfs-progs
Please stop check, plese.
The branch 'it' which I mean is
https://github.com/Damenly/btrfs-progs/tree/tmp1
Ok, sorry I thought you said you had pushed your changes to
https://github.com/kdave/btrfs-progs
yesterday.
So, I went back to https://github.com/Damenly/btrfs-progs.git/tmp1 and
I'm running it without the extra options you added with hardcoded stuff:
gargamel:/var/local/src/btrfs-progs.sy-test# ./btrfsck --mode=lowmem --repair
/dev/mapper/dshelf2
This is okay. Let's wait to see the result.
Thanks
