I have a RAID-5 array with four SATA disks in it.&nbsp; Apparently, two are going bad, so I want to replace them.&nbsp; But, I&#39;m not sure which physical drives to pull.&nbsp; Given the following:<br><br>cat /proc/mdstat<br>Personalities : [raid6] [raid5] [raid4]
<br>md0 : active raid5 sda[0] sdd[3] sdc[2] sdb[1]<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 735351936 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]<br><br>Any suggestions?<br>
