HI
We had very good results Using Trinity Resource Kit(try googling we made a
boot cd quickly and spent a fe minutes reading documentation, actually we
were able to fix the disk and restore the RAQ550 to health ... Too late
though)
We mounted the raq 550 Drives on a whitebox (Anycomputer with CD ROM and
Network card ) ,
The TRK CD has a mountallfs command that mounts all the available partitions
and has an ftp server so you can ftp your files over, That is FTP to the
Whitebox from the New Server and pull all that you need.
Moved a 200 site server in 2 hours (only 80 gigabytes though).
Good Luck

Subject: [coba-e:07404] Data missing after transferring
The scenarios is the following:
2 Drives from a Cobalt RaQ 550.
Cobalt RaQ 550 uses XFS
On 1 drive, I need the fouth partition.
On 2 drive, I need the first partition data.
I have a new box built with Brian's NuOnce 4.5. It has two SATA drives in
software RAID 250 GB.
I boot the system using Knoppix 4.0.
I mount Drive1RaQ550 using a USB enclosure. The partition comes from
/dev/sdc4.
I copy data using the cp command and rsync command from the mounted
partition (/dev/sdc4) to a local partition (/dev/sda7).
I reboot the system into Knoppix 4.0 again but this time I mount
Drive2RaQ550. The partition comes from /dev/sdc1.
I copy data using the cp command and rsync command from the mounted
partition (/dev/sdc1) to a local paritition (/dev/sda7).
I still see all the data from the previous Knoppix session in the /dev/sda7.
I boot the system into CentOS/Bq.
I cannot see the data using an ls-la command.
I can see there is data (79GB) when I do a df -h.
I only see 21 MB when I do a du -sh command.
I booted into Knoppix 4.0 again and do not see the data.
I mount /dev/sda4 and /dev/sdb4. This should be the same partition
(software RAID) from the two internal drives.
I do a df -h and I see sda7 has the full 79 GB while sdb7 has 19 GB.
Theories:
1. The file handles were lost somehow.
2. Software raid may behind the problem. Hence the reason I see
that sdb7 looks like it might be catching up to sda7.
Questions?
How can we monitor any software RAID rebuilding?
Any ideas of saving me the tremendous time of getting to the data without
doing some other method which involves going back to the original disks (it
took me nearly 24 hours to copy the data)?
Any other questions or answers that you might have is appreciated. This is
a box that I need to get back up and running ASAP. However, I still have
the original data on external XFS drives and I am willing to rebuild the BQ
box. However, I need to take the solution what is the least amount of time.
