hi, I'm currently using a 4*750GB SATA RAID-5 under centos 5.2 (mdadm v2.6.4, kernel 2.6.18-128.1.6.el5) which I need to exend by replacing the 750GB disks with 1.5TB ones. since the mainboard has only 4 SATA ports, I need to replace one disk after the other. I came up with the following plan: 1) fail first disk mdadm /dev/md0 -f /dev/sda1 2) remove first disk mdadm /dev/md0 -r /dev/sda1 3) shutdown the server, unplug 750GB sda drive, plug in 1.5TB drive 4) create a linux raid autodetect partition on sda which covers the whole 1.5TB 5) add new device to the raid5 and wait until resync has finished mdadm /dev/md0 -a /dev/sda1 ... repeat steps 1 tp 5 for sdb to sdd 6) grow the raid mdadm --grow /dev/md0 7) resize the xfs filesystem xfs_growfs /md0-mount-point is this the proper way to do it, are there any issues I should know about ? thnx in advance. -- 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
