RN104 - BTRFS Read-Only - No SMART Errors
Hi There, I'm going through a series of unfortunate events that seems to be a bit odd to me, I'd like to hear your opinion. I've start to see strange errors in dmesg for my RN104, related to ...
Mate,
You do not ship hardware meant to be used by unskilled people with software that isn't stable. Is just common sense.
Thousands of hits for my issue all around the globe: BTRFS not working just because.
BTRFS is in development without any serious breakthrough since ever, so much that RH deprecated it, mark my words Suse will too, soon.
I had no drive failures.
I had no power outages.
NAS was heavenly underused.
I am not mad because I lost my data.
I have backup for everything that matters.
I am disappointed because using BTRFS on mdadm slashes the performance of the FS and anyway DOES NOT fixes BTRFS issues it works them around.
I was 1:1000 that had issues . 0.001% does not male a statistics but does pisses me off if I am deliberately the minority that does not matter.
Synology does not differ from Netgear, consumer products that aim to sell. I knew when I bought it it wasn't going to be as stable as a professional solution, I was expecting hw failure, disk failures, write problems due ECC lacks, not a bloody entry in the journal that prevents the whole fs from working. I just wanted connect and use, without having to manage smartmon, thermal sensors, console & madam, etc.
Better off with EXT4+MDADM... for God's Sake even RaiserFS has better recovery tools, you grep the fs. Raiser was famus for being "Glitchy".
The "good" of BTRFS is not in discussion here, I do respect their job and the efforts they are doing.
Why not LVM+MDADM? What is the REAL gain in having snapshots on a home device?
This is about a design flow that exposes possible issues to any RN* running.
Choosing an fs practically impossible to recover data from and additionally that has a write hole ONGOING from years is a gamble.
A gamble that Netgear and Synology are taking at the expenses of people's data, obviously nor of them are responsible if you lose your data.
The FS was accessible RO in Recovery until it wasn't anymore. good night moon.
On the "NAS" is not BACKUP I know, but ONLY BECAUSE I am an IT professional. My father would think that it is Backup, you know why? Because it has BACKUP in the feature list and you buy it in a supermarket.
BTRFS is amazing (on paper) however 99.99% of people won't care about these features adn the one whom knows about them will not use them in an embeed hw, home users needs stability over features. You do not need a gun to catch a fly, you need a fly catcher.
Choosing a stabler combination of software would had definitely made me less bitter.
It is pointless to me to be bitter here and now.
I got away from it, you should too, professional opinion.

Well, in my own professional opinion it is stable (and the BTRFS team does claim that also), so we will have to agree to disagree on that.
Personally, I have four ReadyNAS deployed running OS-6 (one since 2013), and have never lost a BTRFS volume. I did lose one once using ext (the disks were healthy - the failure was the result of an unexpected power cut). Though obviously your experience wasn't as good as mine.
I do agree that the need for independent backups should be more prominently stated.
