Hello all,
I have just upgraded my desktop to F16 from F14 (I skipped F15 because the
live distro did not seem able to run gnome 3 on - now it does
apparently!).
I did a clean install (but with the existing /home partition) and copied
accross some config files (see below).
Now, although F16 works OK I notice it takes a veeeerrry looooong time to
boot. A little investigation led me to this:
[root@localhost ~]# systemd-analyze blame
60374ms mnt-NFSmark.mount
60369ms mnt-datastore.mount
60368ms mnt-stuff.mount
3819ms mdmonitor-takeover.service
....
Now this machine connects to a server running F15 on my home network
(192.168.2.2). This is the /etc/exports on that machine:
cat /etc/exports
/home/mark
192.168.2.4(rw,async,no_subtree_check,nohide,no_root_squash)
/mnt/tempstore
192.168.2.4(rw,async,no_subtree_check,nohide,no_root_squash)
/mnt/datastore
192.168.2.4(rw,async,no_subtree_check,nohide,no_root_squash)
/mnt/f11
192.168.2.4(rw,async,no_subtree_check,nohide,no_root_squash)
The NFS drives on the F16 desktop PC (192.168.2.4) are mounted by /etc/fstab:
192.168.2.2:/home/mark /mnt/NFSmark nfs rw 0 0
192.168.2.2:/mnt/tempstore/ /mnt/stuff nfs rw 0 0
192.168.2.2:/mnt/datastore/ /mnt/datastore nfs rw 0 0
This was copied from the previous F14 install where it worked fine and
there were no such delays during boot.
Why does it now take so long?
How do I troubleshoot further, or - better yet - fix it?
Hi,
This could be related to the network card initializing itself later at the boot process while in the earlier steps, it has marked itself as active. I have seen incidents like this.
Is it possible for you to mount all the NFS mounted FS at the last stage of the boot process. Possibly creating a rc.local file, making it executable and do the NFS mounts from it. This can be one step of debugging.
Another can be to simply add _netdev option in the NFS exports and check whether it improves things.
This is all what I can think of now.
Thanks,
Soham
Thanks in advance...
