Besides the mentioned issues with reusing disks, they also had used and maybe still use some faulty series of Seagate drives e. g.: http://forums.seagate.com/t

So beware of having those installed, under high I/O they will fail at a random instant.
- Udo 13y agoA Barracuda on my Hetzner server failed 1 hour ago. This is the second time I had disk trouble at Hetzner - the first time both RAID disks failed at the same time. However, support is acting incredibly quickly, within 5 minutes of sending the support request they got to work on the server.
- annnnd 13y agoBoth disks failing at the same time might indicate that the problem is with the controller or cables. One of our disks (at Hetzner) died on us a few months ago and unearthed an issue with backups. :( Because of missing data we asked for a data cable replacement first (instead of just replacing the disk) - and it worked. Even more, it works without problems since. YMMV of course. BTW, I have worked with many providers but Hetzner is my favourite. Great support and very few problems.
- Udo 13y agoIn my case I think it actually was the drives though, it was the same model Barracuda. Looks like they're replacing them with Toshibas now, so I'm hopeful. > BTW, I have worked with many providers but Hetzner is my favourite. Great support and very few problems. I'll second this. Support is/was often a horror story for me, but so far Hetzner has been absolutely impeccable. Contrast this with Mediatemple, where I once had to engage in a lengthy support battle with a chain of incredibly ignorant and condescending support staff before being escalated to a senior person who finally, finally admitted I had found huge problem with the cluster. This took several days of intermittent outages, dozens of emails, and a lot of energy...
- zerd 13y agoI also had a double disk failure on my Hetzner server quite recently. The server didn't respond, and when I hardware reset it began rebuilding the RAID, but it didn't say which disk failed. It happened again very shortly. Hetzner changed the cables and it has now been a month without any issues. After the disk failures, however, some of the virtual images I had on there had trouble booting. They were complaining about bad blocks. After running fsck they ran again. The whole experience made me realize that I really need to run on a filesystem with checksumming. Just plain RAID-1 only helps for a limited subset of errors, and only if it is able to detect which disk failed correctly.
- Nux 13y agoI have a couple of ST33000651AS in my server, they failed several times, but the current pair has been running for more than 1 year, I guess they just got a nasty batch. Needless to say, rebuilding 3 TB raid took a long time and downtime and pain... but all in all, it was worth it, considering the prices. I can also confirm support was quite fast, even if some of the replacement drives were not new and some even came with bad sectors lol ... such is life.
