Hi, We decided to give BTRFS a try. We find it very flexible and generally fast. However last week we had a problem with a Marvell controller in AHCI and one BTRFS formatted hard drive. We isolated the problem by relocating the disk to an Intel contoller (SATA controller: Marvell Technology Group Ltd. 88SE9172 SATA 6Gb/s Controller (rev 11) had a lot of problems and I managed to overcome them by passing libata.force=noncq for a couple of weeks, until it failed generally). Now that the disk is on the intel contoller it works fine and data is intact, but whenever I do mount or unmount I see: Aug 10 18:34:47 MyServerHere kernel: btrfs: bdev /dev/sde1 errs: wr 0, rd 0, flush 0, corrupt 166, gen 0 The problem is "corrupt 166" Sofar I did: 1. btrfsck and it reported everything is OK 2. btrfs scrub start /dev/sde1 and it again reported all is OK Am I missing something in my filesystem checks or there is another way to zero the corrupt counter?
