Hello and sorry if this is not the place for a relatively “newbie” question. Five years ago I built a NAS box running on Ubuntu server then-current version. The NAS has 4 SATA drives (the RAID set) and a PATA system drive (for the OS). Now the system drive has failed (click of death). I believe the that RAID data is still safe and sound, but my question is how to proceed in such a scenario. (I do have a backup but it’s fairly old). I do not remember exactly how I created the RAID set, other than being with mdadm and probably RAID 5. I have now replaced the failed PATA drive with a new 32 GB PATA SSD, and installed Ubuntu Server 14.04. The system is up and running and it sees the four SATA drives. I have installed Webmin and I am ready to recover the RAID set. I read the Wiki and it suggests running a “permutation” Perl script. Is this a reasonable thing to do? I could not find much information on a case like this in a Goole search, so any help appreciated.
