 Posted: Mon Mar 28, 2005 11:06 am Post subject: udev doesn't see my new partition |
 |
|
I just repartitioned my second hard disk in view of putting lfs on it. However, I only have /dev/hdb and /dev/hdb1.
/dev/hdb2 and /dev/hdb3 don't exist. Should I make them with mknod, or what? I am loath to reboot, but maybe that's what needs to be done?
Thanks in advance
rav

anything about partitioning changes in kernel log (`dmesg`)? if not, you can use some other partition editting tool and "save" current partition table, so kernel will re-read it...

ok, I did 'fdisk /dev/hdb'
It failed with:
| Code: |
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.
|
There is nothing in dmesg
Does that mean I have to reboot?
Oh btw, this is my disk setup on /dev/hdb:
| Code: |
Disk /dev/hdb: 40.0 GB, 40027029504 bytes
16 heads, 63 sectors/track, 77557 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes
Device Boot Start End Blocks Id System
/dev/hdb1 * 1 38752 19530976+ 7 HPFS/NTFS
/dev/hdb2 * 38753 38946 97776 83 Linux
/dev/hdb3 38947 74792 18066384 83 Linux
/dev/hdb4 74793 77557 1393560 82 Linux swap / Solaris

yeah, this is beacause the block device is "being used", which could mean (IMHO) variety of things. Do you have something mounted from that disk? If so, unmount first.

if other methods don't work, then you'll have.

jkt, you were right. I had completely forgotten to umount /dev/hdb1. Woops! Oh well, that solved it anyway.
Thanks for your help
