Re: [SLUG] connectivity test loop?
Amos, Jiri, many thanks for your comments and suggestions; as it is, I just figured out how to action an sms from sms provider (rather than using local modem), so, I think I can move this off the home pc, and, most of these problems won't be relevant On Wed, March 12, 2014 6:11 pm, Amos Shapira wrote: > Testing for connectivity at the beginning is futile - the connection can -- 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] v-slow raid resync
This isn't going to be an issue with sata vs whatever (though I do suggest running in ahci mode if thats an option) The issue is probably going to be how mdadm is growing the array, it will need to do a buttload of disk access to do that reading and writing every sector on every disk and trying to keep everything in a consistent state while doing so. I don't know if it applies to whatever raid level you are using but is there something like an --assume-clean option you can pass it? I'd also suggest asking in the mdadm list or perhaps IRC. http://forums.whirlpool.net.au/archive/1056831 might be of interest.

You need this to install the “theBay” ROM as well. The process is shown online, but in short you copy the HP BIOS using a DOS/windows installer to a USB stick then copy the “theBay” rom image over the top. You could try to “dd” the image but it does some weird trickery to make the stick bootable for installing the BIOS. You can look for TheBay_Microserver_Bios_041.rar online. The source information is: http://www.avforums.com/threads/hp-n36l-n40l-n54l-microserver-updated-ahci-bios-support.1521657/ And it has all the guff on getting the BIOS onto your N54L and also tips on how to configure it. I have all the files if you need them…. Once again, these are terrific little servers. It has an internal USB port so I just loaded FreeNAS onto an 8Gb USB stick and boot from there. All the internal SATA disks are in ZFS disk pools which do my bidding. As I use ZFS, I went with 8gb ECC memory. I also added an additional Gigabit Ethernet adaptor as the built in broadcom is general networking and I run the second Gig-E port with Jumbo Frames using a gigabit crossover (there is such a thing) to a Mac Mini with the thunderbolt port running Gig-E and doing iSCSI! The Mac Mini runs esxi 5.5 and all the data stores (running various species of Linux) hosted off the HP-N54L. It is like a little tiny SAN, small but perfectly formed…. rachel — Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@exemail.com.au IT consulting, security, programming The more an answer costs, the more respect it carries. — Rachel Polanskis Kingswood, Greater Western Sydney, Australia gr...@exemail.com.au IT consulting, security, programming The more an answer costs, the more respect it carries. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
