What shit happened? Well, of course the SSD-Raid failed, too. Spontaneous massive existence failure. All non-backed-up data lost. Mostly because RAID5 makes things harder to recover data, so I decided to scrap the software raid and go with single disks. Just the device mapper for encryption and one big logical volume per disk.<\/p>\n
That went well for quite some time. An occasional SATA error once in a while, but nothing to worry about. Or so I thought… I could even zero out the unused disks with dd without getting errors. But recently (Oct. 31, 2018) even the single disk failed. No SATA errors, just a stalled rsync to a zeroed out disk. That made me suspicious. The Crucial SSD’s couldn’t be that bad!<\/p>\n
So I decided to change the bus from eSATA to USB. I tried that before, but not with the new external casing. The old one crashed hard when I tried to sync the RAID, so I didn’t think it was an option. But with single drives and a new casing I gave it another try.<\/p>\n
What can I say? I guess it was a faulty cable or something. With USB it works perfectly fine! 4 days and running, not a single error. Throughput is as good as SATA, so I’m keeping my fingers crossed! I really hope that this is the end of this story…<\/p>\n","protected":false},"excerpt":{"rendered":"
