I have had this problem, both with read and write errors but I have only recently noticed it after doing a new install on a headless server and leaving the screen plugged in. I have not had any crashed, data loss or data corruption. Interestingly I have 3 HP ML150 servers but only 2 report this error the spec of each server is as follows: server 1 Operon quad core 2.2 8GB RAM 2 additional PCI-e ethernet cards 4 x 250GB SATA HDD in software RAID10 Ubuntu server 12.04 64bit
server 2 Operon quad core 2.2 4GB RAM 1 additional pci-e ethernet card 4 x 1.5TB SATA HDD in software RAID10 Ubuntu server 10.04 64bit server 3 Operon quad core 2.2 2GB RAM 0 additional pci/pci-e cards 4 x 1.5TB SATA HDD in software RAID10 Ubuntu server 10.04 64bit The Bios settings are all identical. Servers 1 & 2 both have this error, the 250GB drive are getting on a bit but the 1.5TB are brand new. I have tried changing the cables with no effect. The error has been reported on all 4 drives for each machine. Server 3 has not had any reports. The only other difference is the PSU has been replaced in server 3 for a cheap one from amazon! This has lead me to think that is is a power related issue, but since it does not seem to have any impact on performance or data integrity I am not sure I need to be concerned?? My next plan is to use the drive from either server 1 or 2 and put them in server 3 to see if I get any errors. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/550559 Title: hdd problems, failed command: READ FPDMA QUEUED To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
