Grub2/Grub2 Themes Usage Issues
by Stephen Morris
Hi,
I have activated the usage of the Starfield theme for grub2 in
Fedora 17 and I am having issues with it.
1). Scrolling through the list of entries in the menu at boot time
is horribly slow. Every time I scroll with the arrow keys the screen
flashes black and it takes several seconds for the next/previous entry
to be highlighted.
2). I have just upgraded from from an Nvidia Geforce 9800 GT to an
Nvidia Geforce GTX 650 (this is a PCI-E 3 card plugged into a PCI-E 2
slot) and now I can see the graphics for the theme being drawn on the
screen as I watch, whereas with the 9800 the screen draw was
instantaneous. The issue highlighted in point 1) occurs independently of
the graphics card in terms of the same thing happens with both graphics
cards.
3). When I do an upgrade that upgrades the kernel the upgrade
process tries to update the grub2 config and mbr but is unable to
because /sbin/grubby fails with an access denied error even though I am
effectively running in root mode via sudo (implemented via the wheel
group). I have also tried this after switching to root mode via su but
that fails with the same error.
4). Because of the error highlighted in point 3, when upgrading the
kernel, I have to manual run a grub2-mkconfig and grub2-install to
update grub and this process rebuilds the Starfield's Theme.txt file
back to the defaults from the manual customization I have done from
white/grey bold text. The black/black bold text does not work for me on
the Starfield background.
My system is an Asus Sabertooth 990FX R2.0 motherboard, AMD FX 4
GHz 8 core cpu, Geforce GTX 650 2 GB graphics card, 16 GB memory, 256 GB
SSD (this has Win 8 and the boot partitions for Fedora 17 and Ubuntu
12.10 installed on it) and 2 2 TB Seagate hard disks, so from my
perspective computing power is not an issue.
What is the best way to rectify these issues?
regards,
Steve

fedora 16, ext4 corruption
by Ian Malone
Hi,
Is anyone else seeing problems with F16 ext4? I recently moved my
install onto a new harddisc (which is reporting SMART is fine after
running a full test) and did that by making a new ext4 fs (previously
ext3) then rsyncing across. I'm now seeing occasional system 'freezes'
(not hard freezes, but programs can fail to start or freeze. Yesterday
the desktop completely stopped, but I was able to switch to a virtual
console). dmesg reports errors to do with failing to write the journal
and remounting read-only. On reboot an fsck is required, which finds
some fixable problems. Obviously I'm wondering if it's the OS or the
new disc. Was planning an F18 install soon which might help with one
problem but not the other.
Don't know if it's the 'ext4 data corruption bug' or if that's been
fixed. http://www.phoronix.com/scan.php?page=news_item&px=MTIxNDQ

Slighty OT Git Hub/Heroku
by Roger
I have a git hub repository where I have put the Ruby on Rails
development system on Heroku for work by myself and 2 other volunteer devs.
How and/or where would I post the file tree so that we all can work on
the various files, I'm lost on this aspect.
I have explored Github and Heroku but could find no thing obvious.
Can someone point me in the right direction to get this dev working
Thank you in advance

Multiboot question
by Christopher Meng
Hi all,
Recently I'm stucked with multiboot.
I have a disk with following partition:
sd1. 157GB NTFS of Win8
sd2. 55GB including:
sd5. 500M /boot
sd6. 4GB /swap
sd7. 50GB BTRFS Fedora 18
sd3. 55GB not parted
sd4. 32GB not parted
Now I want to install Fedora 17 on sd3 or sd4, but I don't know howto. From
Anaconda I failed evrrytime for not enough space or some other reasons.
So any hints availabe? I think two lvm is the way of installing dual
Fedora, isn't it?
Thanks everyone in advance!

Preupgrade fc15->fc16
by Tod Thomas
I just completed upgrading a FC14 virtual machine running under virtual
box and it went pretty well. Now I am trying to do the same upgrade
only on a FC15 standalone machine to FC16. It looks like it can't find
any of the FC15 repos which is odd since FC14 went so well. Should I
expect this to work or is the FC15 release just too old? Why did the
FC14 upgrade go so well?
TIA - Tod

copy full system from old disk to a new one
by Martín Marqués
How can I pass my whole system from an old SATA disk (which is giving
me some trouble) to a new disk. I have 4 partitions, all of which I
have only passed /home using cp -.a
I'm a bit concerned about the root file system, how to change grub,
and if I'll have trouble with non-regular files from /var.
TIA!

What does "mapping=identity" mean in /etc/exports?
by Greg Scott
Hello -
I'm migrating an old NFS server to newer hardware. /etc/exports in the old environment looks like this:
/shares/IMSHCS01 *(rw,insecure,sync,no_root_squash,all_squash,mapping=identity,anonuid=0,anongid=0
So the old system is exporting the directory, /shares/IMSHCS01 to anyone and everyone who wants to connect, with a bunch of switches essentially making it wide open.
Wonderful.
But on the new system, when I set up /etc/exports the same way, I get this error:
[root@nfs2013 etc]# exportfs -av
exportfs: /etc/exports:1: unknown keyword "mapping=identity"
[root@nfs2013 etc]#
Getting rid of "mapping=identity", my shared directory exports just fine.
I can find no mention of "mapping=identity" in any man pages, but several google references show this option in pasted-in copies of /etc/exports files. My hunch is, this is an obsolete option and no longer supported - but what did it do in case my new server needs to behave the same way the old server behaved?
Thanks

NFS Client: Backup preparation problem
by Amit Karpe
Hi All,
I am not able to access particular directory on client which is mounted
using NFS.
client# ls -l /mnt/tmp
ls: cannot access /mnt/tmp/del: Permission denied
total 0
?????????? ? ? ? ? ? del
I have following disk on server.
server# ls -ld /disk12
drwxrwxr-- 3 root root 4096 2013-02-28 15:53 /disk12
Entry in /etc/exports on server.
/disk12 172.21.123.219(rw,sync)
On client
Entry in /etc/fstab
172.21.123.225:/disk12 /mnt/tmp nfs
fsc,rsize=32768,wsize=40960,rw 0 0
If I used no_root_squash in /etc/exports on server I can access directory
without problem.
/disk12 172.21.123.219(rw,sync,no_root_squash)
What can be the problem ?

This effectively undermines being on one coherent working environment; in
this case, Fedora 18.
The fact that F18 was released w/ Postgresql 9.2 and version of Postgis
(1.5.*) which can't be used w/ 9.2 is disconcerting.
