Hi, all, recently I set up a FreeNAS box: FreeBSD freenas.intern.punkt.de 7.3-RELEASE-p3 FreeBSD 7.3-RELEASE-p3 #0: Sun Oct 17 12:57:33 CEST 2010 root@dev.freenas.org:/usr/obj/freenas/usr/src/sys/FREENAS-amd64 amd64 This is a HP/Compaq Microserver (Proliant N36L). After setting up the system with 4 used 500 GB Seagate drives to find out if FreeNAS would fit our needs, I replaced the drives with WDC RE4 2 TB (WD2002FYPS) and put the system in production to store backups. Yesterday the file system perfomance suddenly came to a crawl and the system log fills with entries like this: ad8: TIMEOUT - READ_DMA48 retrying (1 retry left) LBA=3907027968 ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE WCACHE taskqueue timeout - completing request directly ad8: WARNING - SET_MULTI taskqueue timeout - completing request directly ... Only one of the for drives shows these timeouts. My question: does this necessarily mean I have an isolated problem with that particular drive, since the other three are running just fine, or could there still be someting more fundamental going on? atapci0: <ATI AHCI controller> port 0xd000-0xd007,0xc000-0xc003,0xb000-0xb007,0xa000-0xa003,0x9000-0x900f mem 0xfdfffc00-0xfdffffff irq 19 at device 17.0 on pci0 atapci0: [ITHREAD] atapci0: AHCI Version 01.20 controller with 4 ports detected ata2: <ATA channel 0> on atapci0 ata2: [ITHREAD] ata3: <ATA channel 1> on atapci0 ata3: [ITHREAD] ata4: <ATA channel 2> on atapci0 ata4: [ITHREAD] ata5: <ATA channel 3> on atapci0 ata5: [ITHREAD] ... ad4: 1907729MB <WDC WD2002FYPS-02W3B0 04.01G01> at ata2-master SATA300 ad6: 1907729MB <WDC WD2002FYPS-02W3B0 04.01G01> at ata3-master SATA300 ad8: 1907729MB <WDC WD2002FYPS-02W3B0 04.01G01> at ata4-master SATA300 ad10: 1907729MB <WDC WD2002FYPS-02W3B0 04.01G01> at ata5-master SATA300 Thanks, Patrick -- punkt.de GmbH * Kaiserallee 13a * 76133 Karlsruhe Tel. 0721 9109 0 * Fax 0721 9109 100 info@punkt.de http://www.punkt.de Gf: Jürgen Egeling AG Mannheim 108285
