btrfs is pretty reliable apparently unless you stress it in ways where |
10 |
it is known to be flaky ... and it's now SUSE's default root filesystem ... |

Basically, DO NOT use raid, unless it's raid 1. DO NOT let the disk fill |
13 |
up if you're using snapshots. |

I think one of the reasons it's still got a bad rap, is a lot of SUSE |
16 |
installs fell over pretty badly. And the reason they fell over is that |
17 |
the developers forgot a lot of users don't have powerful machines ... |

The SUSE defaults were to enable snapshotting for upgrades and updates. |
20 |
And not to check the size of disk allocated to / ... :-( so it was not |
21 |
unusual for an update to snapshot, install, run out of disk and BOOOOM :-( |

Made worse by the fact that when they realised this, they didn't try |
24 |
to fix it retrospectively, leaving a lot of time-bombs out there just |
25 |
waiting to go off. |

Fortunately, when I hit this, I had spare disk I could add to the volume |
28 |
and it promptly sorted itself out, but a simple dedicated root should |
29 |
not fill up a 10GB partition (or was it 80? I'm not sure ...). But no, a |
30 |
lot of people have trashed their disks trying to recover from a disk |
31 |
full scenario :-( |
