Note: I forgot that gmane is swallowing my posts to bug-guix and posted
this via gmane, so now I am resending by mail. Sorry if this duplicates!
I am attempting to set up RAID. First, following the doc, I ended up
with system39.scm, attached, excerpt below:
(operating-system
(host-name "g1")
(timezone "America/New_York")
(locale "en_US.utf8")
(bootloader (grub-configuration (device "/dev/sda")))
(initrd (lambda (fs . args)
(apply base-initrd fs
#:extra-modules '("raid1")
#:mapped-devices '((mapped-device
(source (list "/dev/sdb1" "/dev/sdc1"))
(target "/dev/md0")
(type raid-device-mapping)))
args)))
(file-systems (cons (file-system
(device "ssd-root")
(title 'label)
(mount-point "/")
(type "ext4"))
%base-file-systems))
In this config I was attempting to have the array assembled, but not
mounted after the boot. It did not look promissing that 'guix system
reconfigure system39.scm' did not assemble the array. Then as one might
expect, the resulting system boots but the array is not assembled.
After a couple helpful exchanges with Andreas on the devel list, I ended
up with system40.scm, attached, excerpt below:
(define md0
(mapped-device
(source (list "/dev/sdb1" "/dev/sdc1"))
(target "/dev/md0")
(type raid-device-mapping)))
(operating-system
(host-name "g1")
(timezone "America/New_York")
(locale "en_US.utf8")
(bootloader (grub-configuration (device "/dev/sda")))
(mapped-devices (list md0))
;; Add a kernel module for RAID-1.
(initrd (lambda (file-systems . rest)
(apply base-initrd file-systems
#:extra-modules '("raid1")
rest)))
(file-systems (cons*
(file-system
(device "ssd-root")
(title 'label)
(mount-point "/")
(type "ext4"))
(file-system
(title 'device)
(device "/dev/md0")
(dependencies (list md0))
(mount-point "/mnt/md0")
(create-mount-point? #t)
(type "ext4"))
%base-file-systems))
Here the intent is to have the array assembled and mounted after the
boot. It looked promissing when 'guix system reconfigure system40.scm'
assembled and mounted the array (see system40.log). But on reboot the
system hangs with the console showing:
[...] clocksource: Switched to clocksource tsc
And /var/log/sheperd.log contains:
