Hello, My machine is running Software RAID 5 on /dev/hde1, /dev/hdg1,/dev/hdi1. I noticed on the log that suddenly we are getting messages such as :

Similar messages for /dev/hdi and /dev/hdg also, however it seems that /dev/hde has the most and have been occuring the longest.
[root@localhost log]# grep SMART messages messages.1 | grep hde | wc 178 3023 25944 [root@localhost log]# grep SMART messages messages.1 | grep hdg | wc 93 1578 13583 [root@localhost log]# grep SMART messages messages.1 | grep hdi | wc 95 1612 13865
This did not happen a week ago: [root@pathfinder log]# grep SMART messages.2
Checking /proc/mdstat indicates that all the drives are active i.e. RAID is not running in degraded mode.
So, is it that suddenly my drives are failing ? Any comment or suggestion is greatly appreciated.
Thanks. RDB
Smart errors are an indication of a pending hard drive failure. If you are getting this type of error on all the drives in the array and they are all the same age then I would replace the drives as soon as possible.
