trurl Posted March 9, 2016 Share Posted March 9, 2016 My 2x120GB btrfs raid1 cache has never given me any trouble. But I still follow the usual advice about having backup copies of critical data even if it is fault-tolerant. I have a weekly cron script backing up my appdata to another disk in the array.

Lebowski Posted May 3, 2016 Share Posted May 3, 2016 Hey Everyone, I'm new to unraid. It's my first exposure to Linux besides Openelec. So far so good, it's been an amazing learning experience. I have only had my server up and going for a few weeks. I have also built up a new beast for my unraid system, (Supermicro 1151 board with E3-1275-V5 + 32GIG ECC Ram, want this to last me the next 5-10 years) I am using an older 120GIG SSD for my cache formatted to XFS. However I have been looking at redundancy for my dockers and Windows 10VM. I was going to order 2 x 512 M.2 Drives for cache and run BTRFS but this thread has me a little worried about doing it. What is the go? Is it safe to do so? The new CA update for backups looks like an option (need something like this for VM and then we are in business). Has anyone been running a cache pool for a year or so and all ok? I see more negative than positive. Quote Link to comment
gundamguy Posted May 3, 2016 Share Posted May 3, 2016 IDK, I'm using BTRFS now and have been for several months (not a full year) with no problems. Also I saw that BTRFS has more guidance on using btrfsck and recovering from errors now... (as in only do btrfsck as the last possible thing, and use btrfs restore first as it's non-destructive) so maybe recovery tools are progressing. Quote Link to comment
Lebowski Posted May 3, 2016 Share Posted May 3, 2016 Well, I will give it a go and report back, I'll keep some backup's just in case. Quote Link to comment
gundamguy Posted May 3, 2016 Share Posted May 3, 2016 Well, I will give it a go and report back, I'll keep some backup's just in case. Always the best policy. Let us know how it goes! Quote Link to comment
Lebowski Posted May 6, 2016 Share Posted May 6, 2016 Well its up and going, no issues so far. Had to upgrade to 6.2 beta as my drives are nvme. Is it normal for this message in the btrfs status? No balance found on '/mnt/cache' Everything seems ok / balanced. Total devices 2 FS bytes used 83.75GiB devid 1 size 476.94GiB used 85.03GiB path /dev/nvme0n1p1 devid 2 size 476.94GiB used 85.03GiB path /dev/nvme1n1p1 Quote Link to comment
JorgeB Posted May 6, 2016 Share Posted May 6, 2016 Is it normal for this message in the btrfs status? No balance found on '/mnt/cache' Yes, it will only change when doing a manual balance. Quote Link to comment

JonathanM Posted May 6, 2016 Share Posted May 6, 2016 this really bothers me though... why does it say No Balance Found when there is a balance? I could be wrong, but I think it's indicating that there is no balance operation in progress or pending. Quote Link to comment

I spent some time reading through it and its linked info, didn't gain much confidence, but did add some of it to the wiki, the BTRFS section. Quote Link to comment
