Like a few others on this board, I have run into the problem of formatting my whole array when adding one new disk.  I've followed the steps outlined in this previous post and have been able to recover most of my data.

My only problem is I have one disk (disk 1) which is a PATA hard drive.  When running reiserfsck I did not have an md1 device (I'm assuming this is my PATA drive) so I ran it for md2-md5.  What is the correct device name to be able to run reiserfsck on my PATA drive or what command would I run to find out?

All of the data disks will have an affiliated "md" device

 

disk1 = md1

disk2 = md2

disk3 = md3

etc...

If you are referring to the "cache" disk, then you would run the reiserfsck on the disk partition itself.

Type

ls -l /dev/disk/by-id

It will list your disks by model/serial number.  At the very end of the line will be the device name. 

For a PATA disk it will be

../hdX

 

where X = a-z

 

Odds are, if you only have one PATA disk, it will be assigned to /dev/hda.

 

You will want to run the file-system check on the first partition on the disk... in this example, /dev/hda1

Note the numeral "1" at the end of the name, signifying the first partition.

 

Normally you want to use the "md" devices, as they will keep parity in sync as you recover the files.  Since the "cache" disk has no parity protection you can use the /dev/hdX1 or /dev/sdX1 device/partition name.
