Bug#606826: upgrade-reports: release notes should warn about vital NFS mounts during upgrade
Package: upgrade-reports
Severity: normal
Tags: squeeze
Hi.
Basically I had /var/cache/apt, linked to /home/root/apt, and /home was NFS
mount.
After downloding everything using apt-get dist-upgrade -d, i started upgrade.
Unfotunetly in mean time, something broked (probably nscd, nss, or LDAP
authentification),
and NFS mount was still mounted, but files was practically unaccessible.
For example "ls /home" just hangs. And it cannot even be interupted by Ctrl-C.
Nobody could connect using ssh easly (i still managed somehow to login
into root using ssh, and fix problems).
It worked for me without problem when doing small upgrades in lenny,
but apperantly it is a problem of some kind in big upgrade of all packages.
(I use NFS for apt, because my workstations have limited disk capacity,
and I have many of them, so I often download everything on one machine, and
then
remove lock, and use it on others machine to save Internet bandwidth).
I had this issue on 2 machines i tried to upgrade.
I can try reinstalling there back lenny using FAI,
and perform upgrade again to see what is going on exactly,
and record whole session.
(Previously i somehow managed to fix problem, but do not have
logs)
Similar problem could appear if /usr/ is mounted on NFS i suppose.
Thanks.
