I installed tw= o 4 TB drives, created 4 TB partitions but array cannot be resized over 2 T= B. Superblock versoin is 0.90 and kernel version is 3.2.53 - according to l= inux RAID wiki, it should support 4 TB component/array size: > https://raid.wiki.kernel.org/index.php/RAID_superblock_formats#The_versio= n-0.90_Superblock_Format >=20 > Some more info: >=20 > # 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 >=20 > Update Time : Sat Sep 6 23:04:44 2014 > State : clean=20 > Active Devices : 2 > Working Devices : 2 > Failed Devices : 0 > Spare Devices : 0 >=20 > UUID : 9a363004:ad04abfe:2e31e1c3:caf66df4 > Events : 0.77066 >=20 > Number Major Minor RaidDevice State > 0 8 33 0 active sync /dev/sdc1 > 1 8 49 1 active sync /dev/sdd1 >=20 >=20 >=20 >=20 >=20 >=20 >=20 > # fdisk /dev/sdd >=20 > WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdis= k 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?
