Can someone remind me how to give mount options for the root file system to the kernel. Nothing there in the kernel docs.
Just to give a background, i have been playing around with an old 4 cpu hypersparc beast. Making it run with reasonable stablity in smp with everything compiled from ground up with _most aggresive optimization was, well interesting ;) almost flunked courses for that. Its running 2.4.20 with ext3 root file system. But the performance hit between ext2 and ext3 is significant. I was planning to tweak 2 things, the commit interval and the data= option. The problem is if change the data=writeback in fstab, the thing cant boot up cleanly. Dmesg shows that it mounts the the root filesystem initially readonly with data=ordered and while mounting rw fails with "can't change data parameters when remounting". It gets more and more interesting, once i boot up using the root passwd and invoke a mount -t ext3 /dev/sdb4 / -0 remount,data=writeback it fails, but if i just do a remount with no options it remounts, mtab shows its been mounted as data=ordered but dmesg shows its been mounted correctly as data=writeback. So wondering if there is a way to make the kernel boot it initially in ro with data=writeback mode. Hoping that then it would be able to switch to data=writeback,rw cleanly. I have to pass the root= parameter anyway for booting, might aswell add some mount options. -- sreangsu ------------------------------------------------------- This SF.NET email is sponsored by: Order your Holiday Geek Presents Now!
