actually I have another question : is it posssible for a RAID0 fs to “receive” from a “sending” RAID10 ? or do they need to be of the same replication scheme too ? > On Jun 27, 2015, at 10:34 AM, Vincent Olivier wrote: > > ok i’ll go home and rethink my life then ;) > >> On Jun 27, 2015, at

slowdown after one week

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 -- To unsubscribe
