Um ,yeah, there's a problem - it's called BTRFS.

I'm reminded at this point about electoral politics. Example: the party whose representative didn't make it to the presidency bitches about that fact. The reality is that bitching isn't going to change that.
It isn't going to change the adoption of BtrFS.
Agreed. I'm not bitching about it, but I can choose not to use it too. The first and only time I allowed it to install, after a few weeks I ended up with an unbootable, unfixable system. Why? Because / was full , and corrupted, and would only mount ro. The filesystem maintenance tools (if they'd been available and installed) live on /, and / has to be mounted to access them, except you can't repair a mounted filesystem, so you have to unmount it, which means you now have no filesystem checking tools...and of course the system will only boot into emergency maintenance mode, and I can't install the tools needed to fix it because zypper won't run because /var is mounted ro... This was about the time when I reinstalled the system from scratch using ext4...
Just like you hope the prez will do good stuff, we hope that BtrFS will get cleaned up and work properly.
Yes, and it would be nice if the distro packagers would set some sensible defaults at install time, by which I mean settings that make sure your / filesystem isn't going to be unusable in 3 months' time. At least you do have the option of disabling snapshots at install time, but how many people understand what that means and its effects (positive or negative)? Some explanation in the install process would be helpful,(but I guess the standard answer to that would be RTFM...except that these days that would need to be modified to DARTFM (Download and read...). :)
In the mean time you have alternatives.
Vive la choices! :)
Strangely enough the supposedly orphaned ReiserFS got a state of high reliability PDQ. Using ReiserFS on LVM offers many of the supposed advantages of BtrFS, without the hassle of snapshots running amok but without the SSD tweaks.
Interestingly, the Samsumg proprietary ssd management tools only support trim on ext4 (or NTFS on 'Doze).
I'm sticking with ReiserFS for production for the moment. I'll keep a play machine for BtrFS.
Ext4? Sorry, I'm not going to get bitten by inode exhaustion again, and i think having to massively over-provision is a ridiculous strategy. Better to have the integrated b-tree as well as the 'stuffing' of ReiserFS.
Never experienced inode exhaustion, and rotating rust is cheap these days. :) However, none of this venting is likely to be helpful to the OP, so I'll shut up now and go to bed. :) -- ============================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au ============================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
