Hi all,

Ever since I've installed openSUSE 11.4, my /boot partition never unmounts cleanly during a reboot.

I never had this problem with openSUSE 11.3.

Any thoughts?

I've stopped using a boot-parition long ago, but let's have a look at your fstab.

Why is that? People told me that separate the disk on boot-swap-home is the best way to install a linux system. Is there a better way? I am really interesting in that... Kostas

should be root-swap-home, not *b*oot

boot is only needed if you have some special root filesystem grub is not able to read from start (but this may be quite common: LVM or RAID, for example)

jdd

I added /boot because I wanted to try out btrfs and xfs. -- Cheers! Roman "Six by nine. Forty two." "That's it. That's all there is."

I added /boot because I wanted to try out btrfs and xfs.

For what it's worth, I started configuring /boot as a 100-MB partition with ext2 when grub started having problems with reiserfs. Now I use xfs for all non-boot partitions, which has been treating me well with file-systems as large as 30-TB.

I haven't tried btrfs, how is it for large file-systems with many large (~2-GB) files?

Hi Kostas, some boot-loaders used to have a limitation that required /boot to be on the first 1024 cylinders of the disk. The way to guarantee that was to have a small /boot partition in the beginning of the drive. swap space is usually kept on a separate partition/drive for speed. You could just as easily keep a swapfile on your root filesystem, but adding the filesystem layer only makes it (even if only marginally) slower. /home is easier to manage during upgrades and updates if kept separately. /Per -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Urban legend. There is no filesystem layer involved after swapon.

How do you avoid that when you're swapping to a swapfile? -- Per Jessen, Zürich (13.0°C) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

the file's blocks are mapped on swapon and after that the kernel writes directly to these blocks. The only performance penalty you'll see is if the file is heavily fragmented.

Ah, interesting, thanks. -- Per Jessen, Zürich (8.8°C) -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
