sata2 without hot plug?
Hi Roberto. I mean that there is no hot-plug bay, with sliding rails etc.. The drives are connected to the mb using standard sata cables.
check if your sda sdb sdc will change after removing it, it´s depends on your udev or another /dev filesystem
Ok, thank you. That means that if I take care to check the above, and the new drive will be sdb, then taking the steps indicated in my original post will do the job? Best regards. Robi
2011/2/23 Roberto Nunnari <roberto.nunnari@xxxxxxxx>:Hello. I have a linux box, with two 2TB sata HD in raid 1. Now, one disk is in failed state and it has no spares: # cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb4[2](F) sda4[0] 1910200704 blocks [2/1] [U_] md0 : active raid1 sdb1[1] sda2[0] 40957568 blocks [2/2] [UU] unused devices: <none> The drives are not hot-plug, so I need to shutdown the box. My plan is to: # sfdisk -d /dev/sdb > sdb.sfdisk # mdadm /dev/md1 -r /dev/sdb4 # mdadm /dev/md0 -r /dev/sdb1 # shutdown -h now replace the disk and boot (it should come back up, even without one drive, right?) # sfdisk /dev/sdb < sdb.sfdisk # mdadm /dev/md1 -a /dev/sdb4 # mdadm /dev/md0 -a /dev/sdb1 and the drives should start to resync, right? This is my first time I do such a thing, so please, correct me if the above is not correct, or is not a best practice for my configuration. My last backup of md1 is of mid november, so I need to be pretty sure I will not lose my data (over 1TB). A bit abount my environment: # mdadm --version mdadm - v1.12.0 - 14 June 2005 # cat /etc/redhat-release CentOS release 4.8 (Final) # uname -rms Linux 2.6.9-89.31.1.ELsmp i686 Thank you very much and best regards.
