Hi, I have filesystem build up with 5 x 320 GB disks with identical partitions. Disks have 2 partitions and the first one is dedicated for RAID-1 (/dev/md0) and second one is dedicated for RAID-5 (/dev/md1). The disk /dev/md0 is mounted as /boot and the /dev/md1 is prepared for LVM. PE size is 32 MiB and there is 38035 PEs. I am going to remove one 320 GB disk and have already reduced the sizes of existing LV:s. 1) What is the sufficient free PE number before I can imagine shrinking of RAID-5 device? 2) How should I procede after having enough free PE:s?
Are you removing the disk permanently, or do you plan to replace it? -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
