I realise that the designers envisioned something like this, but even with aggressive sub-volumes to handle partial backups, I think this stinks. it sets all my mental alarm bells running. As you've seen, it anything goes wrong EVERYTHING goes wrong. There's a good reason we had partitioning! I understand snapshotting can be carefully configured but the reality is that its obscure and awkward. The policy for something like zypper updates/patches and the ability to roll them back in the manner reminiscent of the mainframe era is distinct from the snapshotting for user space changes and possible accidental deletes. Snapshotting databases is, again, quite a different strategy. I can see that a site that is, in effect, 'mainframe replacement' might warrant this and might warrant sending the admin off for relevant training and having a standby "scratch" system he could practice on (perhaps a virtual machine), but I think its overblown for a home user or just a workstation.
One headache, at least for me. is the journalctl business (I cannot just open up /var/log/messages).
IIR there was a discussion of this earlier this year and some advice on how to run syslog to /var/log/messages in parallel. Hmm. I seem to be doing that :-) I must have paid attention at the time it was posted :-) Do check the archives ...
BTRFS package wise the system has: rpm -qa |grep btrf btrfsprogs-4.0-7.1.x86_64 libbtrfs0-4.0-7.1.x86_64 btrfsmaintenance-0.1-1.1.noarch
I would strongly advise updating your kernel at the very least! There's the old adage about keeping patches up to date. Try one of these. I prefer the first. Kernel_Stable http://download.opensuse.org/repositories/Kernel:/stable/standard/ Kernel_standard http://download.opensuse.org/repositories/Kernel:/openSUSE-13.2/standard/
I am fairly certain I can get balance to succeed after deleting "enough" stuff - key is what is "enough". I deleted yet another batch of data, and btrfs balance is now running, so far, with -dusage=100.
Hmmm. This sounds rather like cutting off your arms and legs so as to reduce the amount of work the heart has to do pumping blood around the system. I would really really really suggest installing a patched and up to date version of BtrFS - the kernel - as well as the utilities (see my earlier email for the repositories) rather than amputating your data. -- "Now look," Forrester said patiently, "progress is an outmoded idea.
