Hello, We have some dedicated servers at layeredtech. Currently new SATA 500Gb drive was added to each server and we now noticed strange problems with all of them: all new sata disks failed under normal load (3-6 Mbit/s I/O). Engineers at data center replaced the drives but they failed again and again. Do you have any experience in working with 500Gb or more SATA drive? OS: FreeBSD 6.1-STABLE #1: Sun Aug 13 20:29:03 CDT 2006 And this is the information from dmesg of one of our servers: ad4: 476940MB <WDC WD5000KS-00MNB0 07.02E07> at ata2-master SATA150 da0 at mpt0 bus 0 target 0 lun 0 da0: <SEAGATE ST373454LW 0005> Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz, offset 63, 16bit), Tagged Queueing Enabled da0: 70007MB (143374744 512 byte sectors: 255H 63S/T 8924C) Trying to mount root from ufs:/dev/da0s1a WARNING: / was not properly dismounted WARNING: /home was not properly dismounted WARNING: /tmp was not properly dismounted /tmp: mount pending error: blocks 0 files 4 WARNING: /usr was not properly dismounted WARNING: /var was not properly dismounted WARNING: /var/tmp was not properly dismounted WARNING: /mnt/sata was not properly dismounted ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=663885183 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=663885183 ad4: FAILURE - WRITE_DMA48 timed out LBA=663885183 g_vfs_done():ad4s1d[WRITE(offset=339909181440, length=16384)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=828848959 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=828848959 ad4: FAILURE - WRITE_DMA48 timed out LBA=828848959 g_vfs_done():ad4s1d[WRITE(offset=424370634752, length=32768)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=885960859 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=885960859 ad4: FAILURE - WRITE_DMA48 timed out LBA=885960859 g_vfs_done():ad4s1d[WRITE(offset=453611927552, length=2048)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=857331839 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=857331839 ad4: FAILURE - WRITE_DMA48 timed out LBA=857331839 g_vfs_done():ad4s1d[WRITE(offset=438953869312, length=16384)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=862600415 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=862600415 ad4: FAILURE - WRITE_DMA48 timed out LBA=862600415 g_vfs_done():ad4s1d[WRITE(offset=441651380224, length=16384)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=907763295 ad4: TIMEOUT - WRITE_DMA48 retrying (0 retries left) LBA=907763295 ad4: FAILURE - WRITE_DMA48 timed out LBA=907763295 g_vfs_done():ad4s1d[WRITE(offset=464774774784, length=16384)]error = 5 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=951794815 ----- With best regards, | The Power to Serve Nguyen Tam Chinh | http://www.FreeBSD.org Loc: sp.cs.msu.su |
