I've started seeing problems with MegaSAS + smartctl on a few R710's that we have:
*megasas: Failed to alloc kernel SGL buffer for IOCTL* I'm getting these errors when trying to test megaraid disks with smartctl: * [r...@houston ~]# smartctl -t long -d megaraid,0 /dev/sda ; dmesg | tail -1 smartctl 5.39.1 2010-01-28 r3054 [i686-pc-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Long (extended) offline self test failed [Cannot allocate memory] megasas: Failed to alloc kernel SGL buffer for IOCTL * The gooogles have pointed me to an issue with RHEL4 and the MegaSAS drivers, however I don't believe that may be the issue here: * [r...@houston~]# cat /etc/redhat-release CentOS release 5.5 (Final) [r...@houston~]# lspci | grep -i raid 03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04) [r...@houston~]# lsmod -i raid [r...@houston~]# lsmod | grep mega megaraid_sas 33277 6 [r...@houston~]# modinfo megaraid_sas filename: /lib/modules/2.6.34.1/kernel/drivers/scsi/megaraid/megaraid_sas.ko description: LSI MegaRAID SAS Driver author: megaraidli...@lsi.com version: 00.00.04.17.1-rc1 license: GPL srcversion: 100645F7D96F25200FE60DB alias: pci:v00001028d00000015sv*sd*bc*sc*i* alias: pci:v00001000d00000413sv*sd*bc*sc*i* alias: pci:v00001000d00000071sv*sd*bc*sc*i* alias: pci:v00001000d00000073sv*sd*bc*sc*i* alias: pci:v00001000d00000079sv*sd*bc*sc*i* alias: pci:v00001000d00000078sv*sd*bc*sc*i* alias: pci:v00001000d0000007Csv*sd*bc*sc*i* alias: pci:v00001000d00000060sv*sd*bc*sc*i* alias: pci:v00001000d00000411sv*sd*bc*sc*i* depends: vermagic: 2.6.34.1 SMP mod_unload CORE2 4KSTACKS parm: poll_mode_io:Complete cmds from IO path, (default=0) (int)* Any help would be greatly appreciated with this bugger. _______________________________________________ Linux-PowerEdge mailing list Linux-PowerEdge@dell.com https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
