Hi Wolf,
Wolf 写道:
But it is not on the path:
root@gnu ~# pvcreate
bash: pvcreate: command not found
Indeed, lvm2(-static) wasn't actually installed on the
installation image!
Commit 0906ce7389c6654fa3d1b3b52c8330eff0256264 fixes that:
root@gnu ~# which pvcreate
/run/current-system/profile/sbin/pvcreate
On IRC I was advised to try guix install lvm2-static, which does
work
(after sourcing the profile), however it does download the
package
from the internet.
The installer image was generated using ‘guix system image’ with
particular Guix version N. Hence, all packages inside that image
are those from Guix version N. (In Guix, there is no ‘package
repository’ distributed separately from the ‘package manager’.)
These packages include the image's ‘guix’ package itself.
Hence, the ‘guix’ you can run in the image will always be older
than the Guix that put lvm2-static in the image, and may contain
older versions of some packages.
You'll have Guix N's lvm2-static in /gnu/store, but ‘guix install
lvm2-static’ will install Guix N-1's version. They might match,
they might not. I guess here they didn't.
That seems pointless, since I already have
one
locally (as seen in the output of find above), so I would prefer
to
use that one.
You can simply
root@gnu ~# guix install /gnu/store/84n[…]-lvm2-static-2.03.1
That might still download $things for $reasons, but they won't
include lvm2-static.
Another question is how to undo the effect of running herd start
cow-store /mnt. I did try the obvious (herd stop cow-store), but
that
does not seem to do the trick. So, how can I do it?
This I don't know either. I always just reboot.
Kind regards,
T G-R
