(Get the code!)
I have this problem on my 10.04 LTS server, with a seagate 1TB usb2 drive I just purchased. (The disk was formatted with EXT4 whilst at home connected to an Ubuntu virtual machine on a Windows host that I then happily copied a bunch of large files to from a Samba share with write speeds approximately 14MB / sec)
Connected the same disk to my server yesterday and immediately hit this bug when trying to move files from the SCSI disk to the Seagate USB. The server is a DL360 G3.
My colleague pointed me at this bug report. I ran the following commands last night after remotely rebooting:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 10.04.3 LTS
Release: 10.04
Codename: lucid
sudo hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 4 MB in 3.93 seconds = 1.02 MB/sec
A woeful 1MB per sec...
This morning I did it again:
sudo hdparm -t /dev/sda1
/dev/sda1:
Timing buffered disk reads: 2 MB in 7.44 seconds = 275.24 kB/sec
which is pretty much useless.
What must I do? It seems to move from an LTS to a more recent non LTS release is the thing to do but this goes against my ideals of LTS
