HELLO.
In lab environment, I create /dev/md0, consisted of 3 partitions. Each partition has 128MB. Because the type is RAID5, there are about 256MB available for data. After mounting /dev/md0 to /var/share/, "df -h" shows the correct size (259MB Free). But the output of "mdadm --detail /dev/md0" shows the following: ... Array Size : 272896 (266.54 MiB 279.45 MB) Used Dev Size : 136448 (133.27 MiB 139.73 MB) ... What does "Used Dev Size" refer to? THANK U. |
