I noticed the following messages on my system:

Personalities : [raid1] [raid6] [raid5] [raid4] 
Md3 : active raid5 sda5[0] sdc5[3] sdb5[1]
      3858519040 blocks super 1.2 level 5, 512k chunk, algorithm 2 [3/3] [UUU]
      [=================>...]  check = 86.0% (1659909504/1929259520) finish=182.1min speed=24645K/sec

What does check status mean and why did this happen?!

iam using ssd for caching other disks ( flashcache module ) if a power failure happened write operations will just stop suddenly and lead to bad sector due to incomplete cache back to devices ( sata disks ) so is there is a way to continue get cache from ssd to devices ( disks ) after server startup, as the cache already stored on ssd?

Many thanks in advance
