My RAID-5 array consists of the first partition of 4 identical disks and is formatted as XFS (no LVM). This array is running out of space and I'm trying to resize it. The disks all have 2 partitions on them (md0 for the first partition and md1 for the second).
This is what one of my disks look like:
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdd1 1 97281 781409601 fd Linux raid autodetect
/dev/sdd2 97282 121601 195350400 fd Linux raid autodetect
Basically I want to grow the first partition and shrink (or delete and add probably) the second, which can be deleted if necessary. However, I haven't found any method of growing the first partition. Is it even possible? (without rebuilding the array 4 times)?
