Hello, I have some problems understanding the following situation (it's a real situation that occurred one of my friends had this but couldn't explain me) so if anyone can point me to the documentation or explain me will be great: Let's say md3 with members: sda6 and sdb6 - if there are some file system errors on array md3, and I'll create a degraded array with only sda6 then run fsck ..what happens if I'll add sdb6 to the array ...first i don't understand from what member will sync begin ...sda6 or sdb6...then if sync will be from sdb6 errors remain - if the sync will be done from sda6 ...will errors on sdb6 get fixed without fsck - if the sync will be done from sdb6 ....i think will get synced with errors ...so sda6 will have errors If i'm wrong or you can help me please reply... My friend that had this situation started to sync data to another disks so he can't help me with this. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
