ZFS

What I want to do? I use my pool to securely store backups, archive my old documents and keep huge family’s photo library. I have new disks. They were tortured with badblocks , so they’re ready to create ZFS pool. I’ve read few documents about different approaches 1 2 3. I wanted to be sure if anything changed during past years. One of articles recommends mirroring over RAIDZ. Resilvering is faster, at the same time putting IO less stress on whole pool. But pool as small as mine, relies on single drive which might die in between and data won’t be recoverable. Eventually, I decided to go for RAIDZ1 for now and in the future I rather move to RAIDZ2. For that, I have to buy one more disk - Black Friday is close, we will see. ...

I used to have RAID (or at least some variation of it) for my main storage. For redundancy, in case of disk failure. I started with some crazy LVM mirrors done on two disks of different size. Sync job was starting on every boot 😄 Then came time for RAID5 on mdadm + LVM for volume management. It was working nice until the moment when disks became bigger. Long array rebuilds or checks, required my PC to stay turned on overnight just to validate if stuff works still. ...
