Re: [SLUG] Adaptec RAID problems
Thanks for your persistence Ben, I reduced the size of the array to a 2Gb RAID 1 and experienced the same problem. I've worked out that I can load more recent firmware using a more recent version of Sun Common Array Manager. The firmware load failed in RHEL so I'll have to wait until Sun has sorted that out. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Adaptec RAID problems
Hi Nick, Actually, I originally had 5x1Tb in a LVM group and that suited me fine. The HBA didn't support RAID for some reason. The only problem was that Fedora 11 udev tended to timeout when attempting to detect the individual disks. The only way to solve the problem was to plug in the SAS cable after the Fedora had booted and the detection was successful. Here is a post on fedora forum and entry in bugzilla: http://forums.fedoraforum.org/showthread.php?t=243493highlight=J4200 https://bugzilla.redhat.com/show_bug.cgi?id=582094 We upgraded the HBA to one which supported RAID and I decided on Fedora 13 (since Fedora 11 is now EOL). In Fedora 13, udev doesn't appear to detect individual disks. I'm guessing that the default behaviour for the new Adaptec driver in this kernel is not to expose physical components of the arrays (expose_physicals=0). I can probably try to override the driver preference and see what the IO is like to individual disks. Perhaps the problem will go away once I've installed the necessary firmware. I'm very tempted to run a chroot Gentoo from within RedHat. I really need a recent version of linux for development purposes, but it needs to sit on a vendor supported OS. I brought up a chroot image as a way to distribute GEANT -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] Adaptec RAID problems
Hi, Thanks for the pointers. Is it possible that the HBA driver loads the firmware onto the drives? I've tried the harddrive vendor (Hitachi), but they don't release firmware updates. I reduced the size of the array to 4x2Tb RAID10 (4Tb redundant). Perhaps I'll try a smaller size to see if I have the same problem. The easiest way to replicate the problem is to run hdparm -t /dev/sda I get about 400kB/s on the problem RAID. The aacraid driver seems to mask single disks. AFAIK This prevents the driver timingout during bootup I've removed all LVMs so I can use modprobe and rmmod to experiment with different module options without restarting. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Adaptec RAID problems
Hi, I am attempting to run Fedora 13 on a SunFire X4140 with an external Sun StorageTek enclosure with 7x2Tb disks. Fedora 13 boots of a single internal SAS drive. The HBA is an Adaptec AAC-RAID (rev 09). I have successfully created a RAID array using the adaptec BIOS. I have also successfully created a logical volume which is 7.99Tb. I attempted to create a filsystem on the the 7x2Tb RAID array from Fedora 13 but it didn't work. The computer hangs periodically and generates kernel warnings. I suspected that it is an issue related to the Adaptec RAID driver, so I downloaded the supported drivers from Sun. http://www.intel.com/support/go/sunraid.htm The most recent drivers for the external HBA adapter as supplied by Sun are at the level aacraid_1.1.5_2463. I compiled these into the Fedora kernel today and recreated the filesystem, however, I had the same problem. I have installed RedHat EL5 on another partition to help with diagnosing the problem. I've rebooted into Redhat and created the filesystem using the same command. This seemed to run perfectly fine (however I stopped it early because it would take several hours to complete). The baseline version of the Adaptec driver installed by Redhat EL5 is Adaptec aacraid driver 1.1-5[2437]-mh4 It appears that there are no hardware issues with the 7x2Tb array. I would prefer not to upgrade the firmware because it seemed to cause problems with RedHat EL5. Is there anyone in Sydney who had experience with running Fedora on Sun/Oracle Hardware? Thanks Robbie.

[SLUG] Fortress .... err Firewall Australia
I am really most concerned about all the side effects of filtering that we are yet to uncover. For example: If I hosted on a dynamic IP, although I have been assured that it is unlikely, how would I deal with the event that my IP has been blocked to other users? Could the federal government consider not blocking domestic addresses and actually enforce Australian law on our own turf? What if I ran a VPN on port 80? How do I even know that I'm on the blocked list? What about lesser known sites such as the Internet WayBack machine? Would any objectionable material result in a blanket ban?

[SLUG] Keeping wife on linux
My wife and I have a shared computer at home, however, I seem to be facing a loosing battle for her experiences with linux to remain pleasant. I am running fedora core 9 with additional packages from the Livna repository Some nuances: * We've not been able to find a way to purchase songs from Yahoo or iTunes. I've tried foxy tunes and wine without much success. * We've had some difficulty with video codecs. Channel nine or ten is using a codec which includes advertisements but only works for Windows Media Player 10+. * I've also played a few DVDs in MPlayer and other players and just get the "Downloading movies is stealing" on continuous repeat. Is there a distro which is more likely to work with proprietary codecs? Or am I just better to stick to FC or possibly Ubuntu and use 3rd party packages as i have been doing? I've been toying with using vmware and running XP SP2, but I think that it would leave me with two systems to maintain rather than one. I may also have to buy a new machine (dual core) to meet the system requirements. Any suggestions? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] Safe samba configuration
I use samba on a mixed OS network. We have several NAS devices and two Fedora workstations which share drives using NAS. I have configured the Fedora workstations to only announce on the local subnet (/24) to prevent inadvertent connections from the wider organization. I implement this by putting the following in smb.conf remote announce = 10.9.136.0/24 I also set local master = no Because I figured that there were other computers more suited to being the master browser (whatever that means) Unfortunately I've been faced with some windows boxes spontaneously not able to browse or connect to the network. It is occasional, but seemed to decrease in occurance when I reduced the use of SMB shares. I'm really keen to find a safe configuration for my SMB shares, but I'm not sure where I would find how to do this. It's very difficult to diagnose which configuration works better without months of investigation. Any help would be greatly appreciated. -- Robbie Barnett [EMAIL PROTECTED] 0431864709 Skype Name: retsil42 -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] SLUG January meeting video (Microsoft QA) is online
Thanks for putting the January meeting online on so promptly. For me, the material has sparked a few interesting conversations with friends in the industry. I've noticed how MS folk tout their openness as though they have solved the interoperability problem in one fowl swoop. I wouldn't want to cause offence to the great people who work there, but in reality, they have only offered a very small window into Microsoft technology under the Open Specification Promise (OSP). Other companies such as Sun Microsystems have been put into a position that they must make some of their largest projects open source in order to have a hope of market share. We live in very interesting times indeed... Thanks, Robbie -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
Re: [SLUG] HFS+ support
I suspect that the cause is poor support for journalling. I created a separate HFS+ partition with journalling turned off.

[SLUG] HFS+ support
Hello, I've recently set up a Mac/Linux dual boot system. I mounted the HFS+ drive using the experimental HFS driver in read/write mode so I could share my user home between both operating systems. Unfortunately this corrupted my HFS file system today and I had lots of lively messages coming from the Linux kernel. I was admittedly in a bit of a rush to get it going, but now I have the time to relfect on my mistakes. Would anyone recommend a way of running Mac/Linux dual boot?

[SLUG] RedHat at UOW
Hi, I have a colleague from Uppsala University, Sweden. He uses ITK/VTK for data processing and manipulation of Medical Images. He currently has a post-doc position which is shared between UOW and a Sydney hospital. He's informed me that UOW would not let him use his RedHat (Fedora Core 3) machine on the campus network because they only allow for approved OSes to connect to the network. Does anyone have any ideas about how to appeal this decision/policy? I completed a postgrad course at UOW. In all my time there I never managed to get any response from the IT department with regards to policy.
