Title:
boot process hangs very often when NFS shares are used
Status in mountall package in Ubuntu:
Fix Released
Status in mountall source package in Precise:
Won't Fix
Bug description:
I'm running up-to-date Ubuntu 12.04.3 with the 3.2 kernel. I have a
FreeNAS box exporting a number of NFS shares. My machine can boot
once-in-a-while but I have problems on practically every boot, that I
need to resolve by rebooting and trying again.
My fstab:
# /etc/fstab: static file system information.
proc /proc proc nodev,noexec,nosuid 0 0
UUID=2f6ca502-9419-4040-a702-2c9dc716dbc5 / ext4
errors=remount-ro 0 1
nodev /ramdisk tmpfs defaults 0 0
silverbox:/mnt/vol1/software /nas/software nfs auto 0 0 # ENROLL
silverbox:/mnt/vol1/videos /nas/videos nfs auto 0 0 # ENROLL
silverbox:/mnt/vol4/backup /nas/backup nfs auto 0 0 # ENROLL
silverbox:/mnt/vol4/home /home nfs auto,exec 0 0 # ENROLL
silverbox:/mnt/vol4/source /home/zyga/source nfs auto 0 0 # ENROLL
silverbox:/mnt/vol4/steam /nas/steam nfs auto,bootwait 0 0 # ENROLL
silverbox:/mnt/vol4/music /nas/music nfs auto,bootwait 0 0 # ENROLL
silverbox:/mnt/vol4/photos /nas/photos nfs auto,bootwait 0 0 # ENROLL
The network between the two boxes is working perfectly over gigabit
wired connection. I can always mount each share explicitly, it only
causes failures a boot. My local network uses openwrt routers and has
correct DNS setup for each machine.
My desktop (the machine affected by this bug) uses network manager
with DHCP connection but I did try static IP before and it had no
effect on the failure rate.
I've added a way to open an emergency tty (patched /etc/init/tty6.conf
to start on startup) and inspected mountall logs (patched
mountall.conf to have --debug, not have --verbose, have console log
and not 'expect daemon'). I'll attach /var/log/mountall.log from a
successful boot below.
I have tried to debug this issue with jodh and xnox on #ubuntu-devel
and got asked to report this and wait for slangasek. I can freely
reproduce this bug and I can assist in debugging if required.
