Subject: cannot re-assmble mdadm array
Date: Sat, 12 Apr 2014 01:18:32 -0600 (MDT)	[thread overview]
Message-ID: <400635298.23842674.1397287112819.JavaMail.root@cds036> (raw)
In-Reply-To: <1250925833.23839319.1397286490552.JavaMail.root@cds036>

Hello,

I have a 4 disk raid 5 array which I can't reassmble after one drive in the array failed and caused the port-multiplier to reset multiple times which messed up the array.

Is there any way to get the other 3 drives back in sync to re-assemble the array?

Thanks,
Andrew


/dev/sdd1 and /dev/sde1 are both good. /dev/sdh1 is good but won't re-add. /dev/sdi1 is the failing drive.
