I installed two 4 TB drives, created 4 TB partitions but array cannot be resized over 2 TB. Superblock versoin is 0.90 and kernel version is 3.2.53 - according to linux RAID wiki, it should support 4 TB component/array size: > https://raid.wiki.kernel.org/index.php/RAID_superblock_formats#The_version-0.90_Superblock_Format > > Some more info: > > # mdadm --detail /dev/md2 > /dev/md2: > Version : 0.90 > Creation Time : Tue Sep 28 16:54:04 2010 > Raid Level : raid1 > Array Size : 2147483520 (2048.00 GiB 2199.02 GB) > Used Dev Size : 2147483520 (2048.00 GiB 2199.02 GB) > Raid Devices : 2 > Total Devices : 2 > Preferred Minor : 2 > Persistence : Superblock is persistent > > Update Time : Sat Sep 6 23:04:44 2014 > State : clean > Active Devices : 2 > Working Devices : 2 > Failed Devices : 0 > Spare Devices : 0 > > UUID : 9a363004:ad04abfe:2e31e1c3:caf66df4 > Events : 0.77066 > > Number Major Minor RaidDevice State > 0 8 33 0 active sync /dev/sdc1 > 1 8 49 1 active sync /dev/sdd1 > > > > > > > > # fdisk /dev/sdd > > WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted. Why are you using "fdisk" even though "fdisk" is telling you not to use it? What does cat /proc/partitions say about the sizes of the partitions?
