Subject: fstrim on BTRFS
Date: Wed, 28 Dec 2011 17:57:15 +0100 [thread overview]
Message-ID: <201112281757.16019.Martin@lichtvoll.de> (raw)
Hi!
With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it
trimmed:
merkaba:~> fstrim -v /boot
/boot: 224657408 bytes were trimmed
merkaba:~> fstrim -v /boot
/boot: 0 bytes were trimmed
But BTRFS does not:
merkaba:~> fstrim -v /
/: 4431613952 bytes were trimmed
merkaba:~> fstrim -v /
/: 4341846016 bytes were trimmed
Is it planned to add this feature to BTRFS as well?
I wish you a relaxed between Christmas and new year time,
