Re: [gentoo-user] Organising btrfs subvolumes
On Fri, 23 May 2014 00:34:25 +0200, Stefan G. Weichinger wrote: I'm working on this btrfs malarkey and have a question about best practice. It is recommended to leave the root volume empty and create a subvolume for the root filesystem which is set with btrfs subvolume set-default, which I have done. Alternative: mount the subvol via option subvolid etc in fstab if you plan to mount different snapshots, for example. I went with set-default for the root subvolume, if I need the root volume I can mount it with subvolid=0. What is the recommended way to create subvolumes that are mounted further down the filesystem? Let's say I was usr and var on their own subvolumes. Do I create them in the btrfs root, which means they have to be mounted from /etc/fstab - or do I create hem below the subvolume called root? I saw more examples mounting every dir via a separate line in fstab (which also adds the choice to mount them with different options, think compression etc). That makes sense, and will be useful should we ever get encryption. My understanding is: * create and use subvols for entities you want to be able to snapshot and rollback individually. * create and use subvols for entities you want to apply special options to: compression, (no)COW, quota ... I would mount each subvol via extra line and create them in parallel ... That's what i ended up doing, thanks. I did have an issue with systemd failing to mount them because the correct symlinks hadn't been created when I run cryptsetup in the initramfs, because it doesn't use udev, but that was fairly easy to fix. That raises another question. Assuming I've done it wrong (well, my wife always does) is there an equivalent to the zfs rename command to move or rename a subvolume? As far as I understand you are allowed to mount the root volume (or academic: any subvol in a higher level) and use plain mv to rename the subvols as if you renamed sub-dirs. rust me to overlook the easy way of doing things, I was looking for an equivalent to zfs rename and never considered mv.

Btrfs is COW, so snapshots only consume space as files change. If you have a read-only filesystem and snapshot it hourly the only space consumed by a snapshot will be a few metadata records. Snapshotting hourly would mostly be a convenience - in theory it should get you time-machine-like functionality just like hourly backups would, but with far less overhead and space use. In practice I stopped doing this, as btrfs can misbehave when you start getting a lot of snapshots accumulated (we're talking thousands). It probably doesn't help that I have VM images snapshotted (though these images have fairly low write volumes - the most active one does most of its writing to an nfs volume so only OS updates, logs, etc change the VM). When snapper would go to cleanup snapshots I'd get panics. I ended up having to write a script that deleted one snapshot every 30min over the course of days to clean up from that. Now I only manually snapshot periodically and I haven't had a problem with it. I suspect that as with many things btrfs-related that it will be worked out in time, though snapshots will always cause fragmentation as long as the filesystem does partial diffs. Rich

There is snapper, which is even in the tree now. It isn't 100% flexible but supports any number of hourly, daily, monthly, and yearly snapshots, with retention policies for each. My problem was that the snapshots were created hourly, but cleaned up daily, which meant 24 deleted in parallel at a time. In general I've tended to notice that btrfs tends to suffer from hurry-up-and-wait issues. It will happily accept a ton of writes (even from an ioniced process) which I imagine go into the log, and then the whole filesystem will come to a halt at the next checkpoint (every 30s by default). It makes ionice just about useless, since the filesystem accepts more data than it can handle, and then blocks even realtime-priority processes while it is catching up. I suspect that it was having a related issue with snapshot removals. 24 huge snapshot removal commands complete in almost zero time, and then in 30s the debt comes due. In order to be a bit more ionice-friendly the filesystem needs to figure out what it can sustain and throttle writes to a reasonable rate. I'm fine with having some allowance for bursting, but having all disk access block for 10-20 seconds isn't acceptable. Oh, and chromium just loves its disk cache - it will happily wait for 20 seconds to read a cache entry that it could have downloaded online in less than a second. Rich

I have a yearly (full), monthly, weekly and daily. Each incremental is against the most recent one of itself or longer period. That means having to keep multiple snapshots active, which I prefer to avoid. You only need to store snapshots for use with incremental backups. So, if all your backups are full, then you don't need to retain any snapshots (and you wouldn't use btrfs send anyway). If your yearly is full and your monthlies are incremental against the yearly then you need to keep your yearly snapshot for a year. If your yearly is full and your monthlies are incremental against the last month, then you only need to keep the yearly until the next monthly. If your monthlies are full then you only need to keep the current monthly assuming your dailies are incremental against those, but if they're incremental from the last daily then you never need to keep anything for more than a day. But, it is a good idea for backing up desktops and laptops. It is really intended more for something like datacenter replication. Snapshot every 5 min, send the data to the backup datacenter, delete the snapshots upon confirmation of successful receipt. In such a scenario you wouldn't retain the sent files but just keep playing them against the replicate filesystem. They'd be fine for backups as well, as long as you can store the snapshots online until no longer needed for incrementals. But, you can always just create a snapshot, write it to backup with your favorite tool (it is just a directory tree), and then remove it as soon as you're done with it. Creating a snapshot is atomic at the filesystem level, though again if you want application level consistency you need to deal with that until somebody comes up with a transactional way to store files on Linux that is more elegant that fsyncing on every write. That would require a method to keep database and filesystem perfectly in sync when they are not necessarily on the same machine. Well, right now we can't even guarantee consistency when everything is written by a single process on the same machine. The best we have is a clunky fsync operation which kills the write cache and destroys performance, and even that doesn't do anything if you have more than one file that must be consistent. The result is journals on top of journals as nobody can trust the next layer down to do its job correctly. Going across machines does complicate things further as there are more failure modes that take out one part of the overall system but not another. However, I'd like to think that an OS that natively supports transactions could at least standardize things so that every layer along the path isn't storing its own journal. In fact, many of the optimizations possible with zfs and btrfs are due to the fact that you eliminate all those layers. Rich

I had upwards of 1000 snapshots on my system before I stopped creating them hourly and and just started having issues with it. I wouldn't really say it is ready for prime time, but it is workable. Of course, you'll still want backups - a million snapshots does you no good if some bug wipes out your filesystem. For one of my ENOSPC incidents I ended up just wiping the entire filesystem and restoring from backup, though if I kept at it I'd probably have been able to fix it. Oh, one other tip if you use btrfs - be sure you have a rescue disk that supports it. Hint, the old Gentoo install CD I had lying around didn't. You'll probably want to keep a rescue CD with a recent kernel and btrfs-tools handy at all times. Rich

Hint, the old Gentoo install CD I had lying around didn't. You'll probably want to keep a rescue CD with a recent kernel and btrfs-tools handy at all times. I have a couple of System Rescue Cd ISOs in /boot and GRUB entries to boot them. I have two because I wanted the latest for btrfs but couldn't be bothered remastering for ZFS so i have an older, premastered image for that. -- Neil Bothwick Mr. bullfrog says: time's fun when you're having flies. signature.asc Description: PGP signature

That means having to keep multiple snapshots active, which I prefer to avoid. But, it is a good idea for backing up desktops and laptops. I'm curious why you have yearly snapshots. I've yet to find any sane production system where a yearly backup had any worth at all. Even monthly is pushing it... Or do you do it to have a decent start point for incrementals? -- Alan McKinnon alan.mckin...@gmail.com

I realized that your VIDEO_CARDS was -i915 then I removed i915 from make.conf Take what I say here with a pinch of salt (building the right drivers with the right settings to work right on the right hardware is, IMNSHO, a huge amount of black magic :-) anyway, I seem to recall that USE=i915 or i965 was the old way of doing things and you needed to know what chipset to build for. Recent code has merged all of that nonsense so all you have to do is set VIDEO_CARDS=intel and emerge can figure out what to build for the hardware it's running on. But I could be completely wrong too, so YMMV :-) # emerge -avtuDN world N ow It detects Intel® Sandybridge Mobile . I should follow the wiki just use intel vesa fbdev Everything is OK though I can't understand why I must remove i915 when Intel® Sandybridge Mobile 's driver is called i915 in kernel modules.
