Question about partprobe ...

[Andreas Rösler]

Hi!

This seems to be not a bug but I do not understand it: Some time ago I 
created via parted partitions on a 2.4TB storage. The only one who could 
not deal with it was fdisk.

This worked for about 2 months with about 3 or 4 reboots. Tonight I had to 
reboot the server again and the partitions did not come up. The parted 
command still found the partitions as they are, but /proc/partitions only 
knew about one partition:

server:\ parted /dev/sdc print
Disk geometry for /dev/sdc: 0kB - 2399GB
Disk label type: gpt
Number  Start   End     Size    File system  Name                  Flags
1       17kB    1636GB  1636GB  xfs
2       1636GB  2399GB  763GB   xfs
Information: Don't forget to update /etc/fstab, if necessary.

server:\ cat /proc/partitions
major minor  #blocks  name
   8    16 2342664192 sdb
   8    17 2147483647 sdb1
   8    32 2342664192 sdc
   8    33 2147483647 sdc1

After 2 really scary hours of seeing myself describing about 20 graphic 
artists the loss of their work (sdb was the backup) I had the intention to 
try partprobe:

server:\ partprobe /dev/sdb

server:\ partbrobe /dev/sdc

server:\ cat /proc/partitions
major minor  #blocks  name
   8    16 2342664192 sdb
   8    17 1952148421 sdb1
   8    32 2342664192 sdc
   8    33 1597271023 sdc1
   8    34  745393135 sdc2

This worked fine, but: I have to do it every reboot. My question to you 
is: Why? Sorry, but I cannot understand it at the moment. The kernel I use 
is 2.6.11 (because of xen), but I also tried 2.6.15.1 without xen.

Otavio: Maybe you could put this in the documentation?
