Failed Drive Replacement

[hvymetal86]

Thank you! Speed has increased significantly:

Code: Select all

root@HvyMtlNAS:/ # cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md0 : active raid5 sdc8[5] sda8[0] sde8[4] sdd8[3] sdb8[1]
      7802449920 blocks level 5, 64k chunk, algorithm 2 [5/4] [UU_UU]
      [===>.................]  recovery = 15.3% (298934996/1950612480) finish=693.0min speed=39721K/sec

Indeed it is much better: 10 hours for recovery a raid5 with 5 2TB disks is the usual time on a 5big2
