Hi. I am currently running FC12. I am working on upgrading my system and going to a 64 bit system, because I know I have some issues in this hardware (slowdowns, internet issues etc.) they have been niggling for a few months now, and I have been gathering cpu bucks to replace it. So first I wanted to run fsck to clean the disks, then do a backup, and finally to replace the system and move to FC14 64 bit. First step did not work. I have seen messages in the boot process indicating errors in the ATA1 section, although the system appears to be working reasonably well (given the niggling h/w errors I knew about). This is new. I wanted to run fsck, so I booted from the install disk for FC12 and opted for the command line without mounting the disks. when I attempted to run fsck for /dev/sda1 I received errors that the system could not run on an LVM volume. How do I overcome this issue? And if LVM's cannot be checked with fsck, how do I ensure that I do not generate LVM's on the new installation of FC14 (sorry, I know that is two questions...) I will send a separate question for the LVM/FC14 issue. Anyway, I could not capture the output message from the command prompt, and wasn't bright enough to write it down. I will try it again if some one needs the exact messages to help me. regards, Les H The following is from the DMESG output: ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 ata1: EH complete ata1: drained 32768 bytes to clear DRQ. ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: ST-ATA: BUSY|DRQ persists on ERR|DF, dev_stat 0x59 ata1.01: failed command: READ MULTIPLE ata1.01: cmd c4/00:00:3f:00:00/00:00:00:00:00/f0 tag 0 pio 131072 in res 59/40:80:c7:00:00/00:00:00:00:00/f0 Emask 0x3 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 ata1.01: configured for PIO0 sd 0:0:1:0: [sdb] Unhandled sense code sd 0:0:1:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 0:0:1:0: [sdb] Sense Key : Medium Error [current] [descriptor] Descriptor sense data with sense descriptors (in hex): 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 00 00 00 c7 ata1.01: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen ata1.01: BMDMA stat 0x65 ata1.01: failed command: READ DMA ata1.01: cmd c8/00:00:00:00:00/00:00:00:00:00/f0 tag 0 dma 131072 in res 59/40:39:c7:00:00/00:00:00:00:00/f0 Emask 0x2 (HSM violation) ata1.01: status: { DRDY DRQ ERR } ata1.01: error: { UNC } ata1: soft resetting link ata1.00: configured for UDMA/100 sd 0:0:1:0: [sdb] Add.
