snapraid-btrfs VS snapraid-runner

Check out: https://github.com/automorphism88/snapraid-btrfs

I've been looking into snapraid-btrfs and snapraid-btrfs-runner.

- Use https://github.com/automorphism88/snapraid-btrfs which allows me to run 'snapraid' sync from a brtfs-snaptshot so the system can continue running 24/7 while doing parity maintenance tasks.

Add btrfs into the mix with snapraid-btrfs and now you have atomic snapshots and don't have to worry about new writes corrupting your snapshot data for that missing drive. And then automate it with snapraid-btrfs-runner, which will automatically check if more than X files were deleted, run the sync, run a scrub, and email you the result. After all that I use Borg Backup to backup content I generate (stuff I can't just download again) to a PC I have at my dad's house off-site. Which has already come in handy when a logical volume for my container data destroyed itself for some unknown reason (that was data on a RAID1 baked LVM volume with XFS as the filesystem).

Btrfs for data and ext4 for parity is one decent combination (btrfs should be absolutely safe enough on single drives) and you can also use something like https://github.com/automorphism88/snapraid-btrfs (read the FAQ if you're wondering why).

Not an answer to your question, but just making sure you are aware of this project: https://github.com/automorphism88/snapraid-btrfs

This is a cross-post from SnapRAID-BTRFS Github issue.

Because I need snapshots and I plan to use snapraid-btrfs.

Yeah this is what I do now. I also use SnapRAID-Runner to provide some extra automation and email notifications. Its a bit less 'safe' than drivepool 2x duplication and doesn't provide the read-striping performance improvements but it does give a single mountpoint for all the drives, makes better use of total disk space and lets you use mis-matched drive sizes.

You just need to use a scheduler and execute Snapraid Runner Script.

a. git clone https://github.com/Chronial/snapraid-runner.git /opt/snapraid-runner

I use mergers and snapraid and monitor my disks using smartmontools. I have the following line in my smartd.conf: DEVICESCAN -o on -H -l error -l selftest -t -s (L/../01/./08) -m [email protected] My postfix main.cf: relayhost = 192.168.0.27:8025 I then run https://github.com/YoRyan/mailrise in a docker on both my NUC VM Hosts which converts smtp emails to pushover messages. Every night at 1AM 0 1 * * * python3 /root/scripts/snapraid-runner.py -c /root/scripts/snapraid-runner.conf > /dev/null 2>&1 I run a snapraid sync and scrub using script from https://github.com/Chronial/snapraid-runner and scrub 20 percent of the array every night. I have it set to only email on error but you can have it email on success as well. I also use the SMART Application in LibreNMS (https://docs.librenms.org/Extensions/Applications/#smart) to graph the temperatures as well handle the temperature alerting.

Just looking to move to SnapRAID from Greyhole, and I notice a lot of chatter regarding https://github.com/Chronial/snapraid-runner.

I am just getting snapraid up and running. I've seen a few different scripts to automate it. Two that have caught my eye are snapraid-runner, which seems commonly suggested. I also saw this script by Zack Reed, and it seems promising as it automates some other items (like pausing docker containers).

I am currently using https://github.com/Chronial/snapraid-runner as my runner every 4am and currently I am experiencing syncing my CCTV folder which always change because of the recording, and as well as my download folder.
