Public bug reported:
Binary package hint: upstart
Distro: Ubuntu Lucid AMD64 Server daily build 2010-02-15
I think this is a problem with upstart, apologies in advance if it's
not. In installing Lucid on a new server, I discovered that grub2 has
problems with large / partitions (see Bug #523543). Since both www and
Maildir want to reside in /var, this partition can get rather big. My
brilliant solution was to make a 50GB / partition and a 3TB data1
partition, with /home and /var being soft links in / to /data1/home and
/data1/var, respectively (cat of /etc/fstab below).
Unfortunately, this doesn't work. Something called ulookahead or something
like this fails because it can't find /var/run, presumably before the /data1
partition has been mounted. Since fs_passno (the 6th field in /etc/fstab) is
presumably only used for file system checking, my conclusion is that /var can't
reside on a partition other than / now?
[My technique for accomplishing the preceding was to do a clean, generic
install of Lucid server to the 50GB / partition, reboot using the Karmic Live
CD, mount / to /mnt, /data1 to /mnt/data1,
cd /mnt; mv ./home data1; mv ./var data1; ln -s data1/home .; ln -s data1/var .]
The combination of grub2 can't handle large / partitions and /var must
live in / is problematic for sites with lots of IMAP mail and/or a large
webspace.
