SUMMARY: How long does `growfs' take?
2007-12-24 21:41:00
mission-critical filesystem. Replies were overwhelmingly positive (no point
in actually quoting them, I reckon) but salient points are:
- check your backups first
- expect the job to take `about as long as newfs would take on the extra
disk, plus a bit extra while the disk previously in use is skipped past'
- under the hood, `growfs' just uses `mkfs' just like `newfs' does, but with
undocumented options that skip disk already in use
- it just works, as far as anyone was prepared to admit: I didn't receive
a single horror story
- it can be done `live', so to speak, particularly if -s is used to make it
incremental, but the `vote' was heavily in favour of doing it outside
prime time, especially for a significant chunk of space.
So, the upshot is that I'm going to leave it until next Tuesday morning at
about 0730, having done an extra full backup overnight.
Thanks to everyone that responded. I resigned from this list a while back
because it was a bit too noisy for me, but I think that was probably a bad
choice.

Does http://www.cs.stir.ac.uk/disc.html apply? Beats me.
