Subject: Balancing subvolume on a specific device
Date: Fri, 19 Aug 2016 19:09:48 +0200 [thread overview]
Message-ID: <df03a71c-8558-520c-af1b-ffb152f65a7d@davideddu.org> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 710 bytes --]
Hello,
I have a btrfs filesystem spanning over two drives: an SSD and HDD.
Label: 'Android Dev' uuid: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx
Total devices 3 FS bytes used 32.08GiB
devid 1 size 21.95GiB used 12.00GiB path /dev/sda2
devid 2 size 33.22GiB used 12.01GiB path /dev/sda3
devid 3 size 53.10GiB used 13.01GiB path /dev/sdb2
(sda is the SSD, sdb is the HDD)
I've got these subvolumes in the filesystem:
ID 258 gen 708 top level 5 path cm13.0
ID 259 gen 708 top level 5 path ccache
ID 269 gen 708 top level 5 path omni
I would like the ccache subvol to always be stored on the SSD, unless no
disk space is available. Is that possible?
Thank you
