Subject: slowdown after one week
Date: Sat, 11 Jul 2015 08:46:47 +0200 [thread overview]
Message-ID: <55A0BBD7.5000400@profihost.ag> (raw)
Hi,
while using a 40TB btrfs partition for VM backups. I see a massive
slowdown after around one week.
The backup task takes usally 2-3 hours. After one week it takes 20
hours. If i umount and remount the btrfs volume it takes 2-3 hours again.
Kernel 4.1.1
Greets,
Stefan
