I had a totally mysterious problem involving one of the mounted partitions: an external USB RAID. I was logged into the ge233 account last night and everything was fine; when I came in this morning and did an ls this is what I got: .../class4/ge233> ls ls: reading directory .: Input/output error When I checked for the device file (/dev/sdb1) it was totally gone. I rebooted and got the following msg on reboot: usb 1-6: device descriptor read/64, error -110 and Resource Conflict - PCI mass storage controller in slot 01 Bus:04, Device:00, Function:00 The first few times to reboot failed, even when I dropped into run level 0 and tried to fsck /dev/sdb1. It just wasn;t there. I finally plugged the drive into a different USB slot and it worked ok. But this was all very alarming. I couldn't find anything in the log files which indicated a fault, nor in dmesg. Any thoughts? 1. Where can I find more information about the error.? I assume that this is a hardware error with the USB port. 2. If this is a software error, how can I get the storage controller in working order? Thanks. 1. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
