The following reply was made to PR kern/107608; it has been noted by GNATS. From: Lars Engels <lars.engels@0x20.net> To: bug-followup@FreeBSD.org, kleister@1a-infosysteme.de Cc: Subject: Re: kern/107608: Raid Problem beim Zugriff auf Raid Date: Sun, 7 Jan 2007 22:52:14 +0100 --Pbi2MkfjSbXbI4MN Content-Type: text/plain; charset=iso-8859-15 Content-Disposition: inline Remko asked me to translate the pr from german to (bad) english. ------------------------------------------------------------------ Hello, following problem: The server runs under heavy load without any problem for about a week. Then, when the swap is accessed, the whole system freezes with this error message: swap_pager: indefinite wait buffer: bufobj: 0, blkno:2, size: 4096 swap_pager: indefinite wait buffer: bufobj: 0, blkno:18, size: 4096 swap_pager: indefinite wait buffer: bufobj: 0, blkno:5, size: 4096 The System hangs and needs to be resetted. I already googled the problem and found other people having the same problem but related to RAID cards. The RAID doesn't get destroyed then. tw_cli /c0 show all /c0 Driver Version = 3.60.02.012 /c0 Model = 9500S-8 /c0 Memory Installed = 112MB /c0 Firmware Version = FE9X 2.08.00.006 /c0 Bios Version = BE9X 2.03.01.052 /c0 Monitor Version = BL9X 2.02.00.001 /c0 Serial Number = L19404A5400107 /c0 PCB Version = Rev 019 /c0 PCHIP Version = 1.50 /c0 ACHIP Version = 3.20 /c0 Number of Ports = 8 /c0 Number of Units = 3 /c0 Number of Drives = 8 /c0 Total Optimal Units = 3 /c0 Not Optimal Units = 0 /c0 JBOD Export Policy = off /c0 Disk Spinup Policy = 1 /c0 Spinup Stagger Time Policy (sec) = 2 /c0 Auto-Carving Policy = off /c0 Auto-Carving Size = 2048 GB /c0 Cache on Degrade Policy = Cache Off Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy ------------------------------------------------------------------------------ u0 RAID-10 OK - - 64K 130.365 ON OFF u1 RAID-5 OK - - 64K 465.641 ON OFF u2 SPARE OK - - - 232.877 - OFF Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 69.25 GB 145226112 WD-WMAKE1901350 p1 OK u0 69.25 GB 145226112 WD-WMAKE1901550 p2 OK u0 69.25 GB 145226112 WD-WMAKE1902083 p3 OK u0 69.25 GB 145226112 WD-WMAKE1901530 p4 OK u1 232.88 GB 488397168 WD-WMANY1038026 p5 OK u1 232.88 GB 488397168 WD-WCANK2644746 p6 OK u1 232.88 GB 488397168 WD-WCANK3893478 p7 OK u2 232.88 GB 488397168 WD-WCAL76951640 Remark: The problem didn't occut in FreeBSD 5.5. How-To-Repeat: Only with RAID card. I also have the same problem on other RAID machines. I rule out hardware issues. Fix: Deactivate swap, which isn't that nice... --Pbi2MkfjSbXbI4MN Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (FreeBSD) iD8DBQFFoWuOKc512sD3afgRAsllAJ0fTEd2PI3kIr0wdikFcxw+bG4UKwCeMIIu TBuUe9BMkaFGAyjCmguB4KY= =cPTw -----END PGP SIGNATURE----- --Pbi2MkfjSbXbI4MN--
