| 1387809 | 2014-11-09 05:49:00 | I use an old Pentium4 with 2Gb ram and running Amahi free its linux command line to set up. Mines been running for 3 years non stop except for when we moved house | gary67 (56) | ||
| 1387810 | 2014-11-09 15:56:00 | I agree that RAID is not a substitute for backups but I would rather let an array rebuilt than restore my data from a backup. Ignoring the fact that home/software RAID might be 'rubbish' because you should do your research before putting your trust into any solution. | WarNox (8772) | ||
| 1387811 | 2014-11-10 06:14:00 | People need to understand that the point of RAID, which is the ability to span onto multiple disk, increase iops and minimise downtime, backups is a completely separate issue. This. |

| 1387812 | 2014-11-10 08:04:00 | Thanks for all your help. As an update I appear to be in the process of recovering the files to another backup drive. Pulled the discs, noting their locations in the NAS. At this time the NAS indicated only 2 x live HDD's and 2 missing HDD's which mean my Raid 5 setup had failed. I then tested each disc individually on my desktop using Crystal disk checker and it identifed one broken HDD ( the one making a clicking noise) and 3 healthy HDD's. "Interesting" I thought and this backed up some reading and the fact that 2 drives failing at an identical time was a little unlikely but could happen. I know the NAS would allow me to run stuff, albeit like a three legged horse, if it could read all three working drives. Re-installed all four HDD's into the NAS and it again indicated Dead 2 and 3 HDD. Powered it down, pulled the clicking HDD out and it rebooted, did some checking then popped me up a NAS folder under network. With eyes closed I clicked on the files and they opened ! I am now copying everything across to another HDD.. The NAS indicates its now unprotected and further disc failures will render the data useless. Prior to inserting a new disc and about 2 days to rebuild stuff I felt more inclined to backup everything first. Lessons learned re backing up etc and again, thanks for the information. Any ideas why one failed HDD would also trick the NAS into thinking another of the drives had failed as well ? So far I've backed up 2TB and about 2.5 to go ! |
