Re: LVM activation on boot hangs after crossgrade

It seems that the command /sbin/lvm pvscan --cache --activate ay 9:0 from the Systemd unit lvm2-pvscan@9:0.service is hanging and blocks all subsequent lvm activities. Am Fr., 25. März 2022 um 20:40 Uhr schrieb Reiner Buehl < reiner.bu...@gmail.com>: > Hi all, > > I am crossgrading my Debian

Re: LVM passphrase

you can add a key to swap. and place this somewhere in the root partition. the key must known by /etc/crypttab, so it should ask only once. Am 28.12.21 um 07:39 schrieb Polyna-Maude Racicot-Summerside: > Hi, > I got two logical volume on my hard disk. > One is the swap > Other is the root > Both
