dev/md2 on /home type ext4 (rw,relatime,data =ordered )Īs the disks are currently mounted by default, to remove a disk from the RAID, we first need to unmount the disk, then simulate a failure, and finally remove it.

We can see that /dev/md1 consists of 21GB and /dev/md2 contains 98.5GB. dev/sdc3 233385984 234432511 523264 82 Linux swap / Solarisĭisk /dev/md1: 21.0 GB, 20970405888 bytesĢ heads, 4 sectors/track, 5119728 cylinders, total 40957824 sectorsĭisk /dev/md1 doesn 't contain a valid partition table Disk /dev/md2: 98.5 GB, 98520989696 bytes 2 heads, 4 sectors/track, 24052976 cylinders, total 192423808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md2 doesn't contain a valid partition table I/O size (minimum/optimal ): 512 bytes / 512 bytes Sector size (logical/physical ): 512 bytes / 512 bytes
