With my old Tyan S2895 (dual opteron, Debian amd64 wheezy) motherboard the CPU fan does not run anymore, even on replacing the power source (I had long ago removed one of the two CPUs). Unfortunately a couple of weeks work is stored in the two mirror raid HDs and was not saved externally. I urgently need those files.

At the same router used for the Tyan I also have a working GA-X79-UD3 with two mirror raid HDs (Debian amd64 jessie). I use the latter for number crunching with two GTX680 and I am badly organized for the web there, actually never raising the Xserver. In order to recover the files, is that possible to attach a HD from the Tyan to the rear SATA ports of the Gigabyte (power to the HD from an external powersource)? The ones I can see are labeled eSATA (Maxwell ports?). Or should I use internal ports? And which procedure, as I never had the need to recover from external HD.

I also have inherited a box with P7H55D-M PRO motherboard with Intel Core i3 CPU running microsoftwindows and unused. I would like to remove the HD and install there the two HDs from the Tyan (should I find the way to install at least 8GB RAM, which is the minimum to run my graphic codes). Any hope that I'll get the Tyan HDs running without reinstallation of Linux?

Thanks for kind advice.

Read 'man mdadm', attach disks to (whichever) port and 'mdadm --examine /dev/sd[a-z];' then 'mdadm --assemble --scan;'?

This should help-
Mdadm - manage MD devices aka Linux Software RAID

I could transfer the mirror raid HDs from the tyan (amd) to the Asus (intel) motherboard. No need to reinstall linux, no need to rebuild arrays. On the internal lan, a simple yes at ssh was enough. It saves the same name despite different macaddress. the power of linux once again. chiendarret
