2013-12-29 17:57:31 penalvch description After updating the to kernel 2.6.32-40-server (from 2.6.32-33-server), our MD device decided to show up as only a fraction of it's previous size. With the previous kernel, md0 shows up (correctly) as 85681.66 GiB, but with the newer kernel it shows up as only 8192.00 GiB - a serious order of magnitude different! Needless to say, with the incorrect size being reported/used, the md device is unusable and prevents access to the partitions on it.
