RAID Part 1: RAID can fail and lead to data loss
So? your point being...?
After resuming to solve my problem, I noticed during comparing of outputs of btrfs checks, that each run reported quite random errors. mdadm never ever reported any problem, there was no unclean stop/unmount or shutdown at all. But running a check of the RAID 1 array, there are mismatches (/sys/block/md2/md/mismatch_cnt shows around 15k at 20% progress). smartctl not showing any problems, repeated selftests are ok. What can have caused this? I am still wondering if this "flush" can cause this: [393168.772025] ata3.00: exception Emask 0x10 SAct 0x0 SErr 0x1810000 action 0xe frozen [393168.772030] ata3.00: irq_stat 0x00400000, PHY RDY changed [393168.772032] ata3: SError: { PHYRdyChg LinkSeq TrStaTrns } [393168.772036] ata3.00: failed command: FLUSH CACHE EXT [393168.772041] ata3.00: cmd ea/00:00:00:00:00/00:00:00:00:00/a0 tag 19 res 40/00:94:c0:26:9c/00:00:08:00:00/40 Emask 0x10 (ATA bus error) [393168.772043] ata3.00: status: { DRDY } [393168.772046] ata3: hard resetting link [393172.792055] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [393172.793691] ata3.00: configured for UDMA/100 [393172.793695] ata3.00: retrying FLUSH 0xea Emask 0x10 [393172.793889] ata3: EH complete [394038.449156] BTRFS error (device md2): parent transid verify failed on 51072286720 wanted 132076 found 86207 [394038.463093] BTRFS error (device md2): parent transid verify failed on 51072286720 wanted 132076 found 86207 the difference between the transactions is quite big > 45k - never been written physically to one mirror device? -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 Comment: Topal (http://freshmeat.net/projects/topal) iQIcBAEBAgAGBQJYY88jAAoJEIiaa+Y8YDPuCDMP/320iixWg2r6hTT+AQM7yE3R Wv9cDUTMgW5Uc/X8zMoK+CqZUAS1QfiNL5pUeo9esRfrGZKAmgPvHPHHxRaVqmld qDd3yiR9WYQ8FCS9GD+S2YOrFf2KDhUNNk6VLT2ogcAGSGx7AwOJNPSKHGrPCvqH dt012Q9PcCBOYz1NKH+53BoN51y5ftdEfJsoGYl4Dw2I79niJzP6mFkV6uZ5bOti SU6QB81tVz4v/TWPHh9CyQll/djJ/+YOQwLQZCf2ibvrdd8bCiqqGuRgMwiK61Ns HnAcSk+7RXzAMOAzua+cMYSHE4BqhpIexZKct+vJPItjnvJVV3csasy/vVneLzPV 4JkOzGAJ6BNMp9nMxb4/4WUzVrdRxA6vVRi0sBMkZlcAHjBMTzCD48ZLFeXXuiqG nRXFc07dW4PPgo/QZpKSmdUMWY8gh5KOF0xMerO4GYW+E62pPYoLAcp6AqzMlhkf btQWSSBR0JTh7b2pl701+ZMyuyEUNOeArMBoFZQKMtOr0VQePfazLTV43H4nWhx6 QL8iziv3cVupQ7NCc4qHMf1kDBp+Xp23euKstpCSqlPN0Puwp3fwoCkEv5fYysw1 T6aH0mix8Cbh6MlBaubKzrE+agTHrQNHXDLhzrrmhskcSbKdyzFz/diFug1E70Qw xwMSXQyQ9PRzIq7nnu83 =IxFq -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
