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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/624510 Title: Copying To USB Is Very Slow In Ubuntu 10.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/624510/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
