Re: I2O support?
Hi guys - could someone please tell me if any Linux kernel currently has support for I2O (Intelligent Input/Output)? 2.3.x we have support for PCI based I2O devices talking I2O lan, I2O scsi and I2O block to I2O spec 1.5. Linux 2.2 has a board specific driver the Red Creek VPN card and you can get a board specific driver the DPT Decade/Century/Millenium series cards While I'm here - does anyone know what is a decent amount of I20 Cache for a RAID controller? We only seem to have 16Mb out of a possible 128Mb.. it has been suggested that this could be the cause of an IO bottleneck we're having with an HP NetServer LH4... Unless the system is unusual you should get better performance by increasing main memory rather than disk controller cache size. How much you want on the board is obviously vendor specific. Alan
Re: LOTS OF BAD STUFF in raid0: raid0145-19990824-2.2.11 is unstable
i/o buffers that just gets exacerbated by other problems, heavy I/O, cache problems (like overheated CPU), cables, etc. Overheating CPU's corrupt memory, fail cache coherency and do other things of that nature. On an x86 box an overheated CPU is a loose cannon. It can cause almost anything Alan
Re: Please Help - SCSI RAID device very slow
Does anyone know how I stop the MegaRAID using the onboard INTEL SCSI Controller? (i960) It should be using my SYMBIOS card...??? An i960 isnt a scsi controller. If you want to use the symbios directly load the ncr53c8xx driver and not the symbios driver. I'not totally sure if that will work but it is at least the right driver. That will basically cut out use of the megaraid totally
Re: Please Help - SCSI RAID device very slow
I do want to use the hardware RAID.. I think I have been looking at this for too long.. I now think the INTEL i960 IS the MegaRAID controller.. I didn't realise it was registered as a PCI device... How come it connects to the Symbios controller? Linux | [MegaRAID] ( Does raid stuff, drives scsi card) | [Symbios] ( SCSI card, does scsi not raid) | DISK
Re: Status of RAID in 2.2.11
Side question... I noticed that the KNI stuff was stripped going into 2.2.11-ac3 (rightly so), so is 2.2.12 going to be a target to get all the KNI stuff working? or perhaps somewhere in .12-acX? Probably 2.3 Alan
Re: Status of RAID in 2.2.11
I'm sure most people on this list are *very* interested in seeing the new RAID stuff go into the stock kernel, especially considering the fact that the current in-kernel RAID code is simply broken in many cases, and doesn't provide essential features such as background reconstruction. I think so too. We have in the past been prepared to do this sort of stuff. 2.2.11 did it with ISDN and I heard few moans, 2.2 at some point needs to do this with the knfsd update. I'd prefer it didnt happen but sometimes it does. In this case people have been asked to use the new tools for a while now Alan
Re: AMI MegaRAID driver update
I tried to use this with a SMP, 2Gb kernel (__PAGE_OFFSET set to 0x7000 For 2.2.* set it to 0x8000 as the 2.2.1 page.h should be telling you to do now Alan
Re: Tar (but not cp) is incredible slow on certain dirs; request for comments/solution ideas/clues.
During the slow down, top claims system is well over 90% percent idle, CPU time consumed by tar and general system time spent is virtually zero You have NIS configured in /etc/nsswitch.conf but are not running NIS
Re: 2.1.129: oops during boot from raid
I thought for a moment that it might be a hard-to-find IDE driver bug, but I see that Andreas managed to get it to happen on a SCSI-only RAID0. Im not sure its MD related either. I've had two 2.1.129 crashes now where the block devices size table got smashed (ie it died in a hail of device 08:02 only supports [hugenumber] sized blocks, and some spontaneous reboots. .126 was ok, .127 and .128 basically died in seconds due to the NFS problems Alan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
