Re: [Dump-users] Slow dump

[Kenneth P. <sh...@se...>]

More data. Still using 2.6.9_1.6_FC2 stock Fedora Core 2 kernel. I mounted 
this time like this:

mount //bigiron/BigBackup /mnt/Backup -t cifs -o 
user=ken,password=xxxx,forcedirectio,wsize=65536,rsize=65536

A regular cp still takes a long time, but dd looks good:

time dd if=/home/ken/tmp/DesertCombat_0.7_Full_Install.exe 
of=/mnt/Backup/test bs=65536
9460+1 records in
9460+1 records out

real    1m3.014s
user    0m0.079s
sys     0m12.475s

Alas, dump with 1 MByte transfers requested is still only getting 530 kB/s. 
So it looks like it's back in dump's court. Dump command is:

dump 0u -b 1024 -Mf /mnt/Backup/sda1.dump -Q /mnt/Backup/sda1.qfa -B 
1000000 /mnt/sda1 -j9
