Hot swap failed software RAID drive with Windows Server 2008




Does Win2k8 natively handle hot-swapping of a hard drive?



I have an existing server with 2 hard drives in it that are currently setup in a hardware RAID-1 configuration; they are each hot-swappable. I would like to switch them from being hardware to software RAID-1. If Windows Server 2008 were to handle the RAID-1 for these 2 drives, would Windows handle the hot-swapping just like the hardware solution does right now? (No rebooting, no fancy scripts, etc.)



ADDENDUM: The situation is that I've got a Dell PE 2950 with 6 3.5" SAS drives; there are currently 3 RAID-1 volumes managed by the RAID card. I would like to replace the drives in one of those volumes with SSDs. It appears the consensus is that, even for RAID-1, TRIM isn't supported by most RAID cards. So the next thought was, "what if the OS handled the RAID-1? then it could pass TRIM through". Unfortunately, the next obvious question was whether or not the OS could handle the hot-swapping. And, of course, beyond even that is the possibility that the RAID card won't support both SAS and SATA drives at the same time. ...but these are independent questions, only one of which was asked up above.


Answer



Hot-swapping is typically supported in the hardware and drivers; if the controller isn't set to do it, you're asking for problems yanking and inserting drives.



Software RAID normally requires a shutdown and switching of the drives.

iLO 3 Firmware Update (HP Proliant DL380 G7)

The iLO web interface allows me to upload a .bin file ( Obtain the firmware image (.bin) file from the Online ROM Flash Component for HP Integrated Lights-Out. ) The iLO web interface redirects me to a page in the HP support website ( http://www.hp.com/go/iLO ) where I am supposed to find this .bin firmware, but no luck for me. The support website is a mess and very slow, badly categorized and generally unusable. Where can I find this .bin file? The only related link I am able to find asks me about my server operating system (what does this have to do with the iLO?!) and lets me download an .iso with no .bin file And also a related question: what is the latest iLO 3 version? (for Proliant DL380 G7, not sure if the iLO is tied to the server model)

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...

linux - How can I get my mediawiki to stop thinking I have cookies disabled?

I've searched half a day for how to resolve this issue, and can't figure it out. Shortly after I made my wiki a simple private wiki according to the instructions at Mediawiki's website, it started giving me this weird login error message: Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again. If I remove those private wiki settings, the error disappears, even if I try logging in. But I need it to be a private wiki for only my team. So what do I do? Here's what I've done so far. Just to be safe, after ever change, I try rebooting Apache using: sudo /etc/init.d/apache2 restart In my php.ini file, I have the following set: session.save_path = "/var/lib/php5" session.cookie_secure = secure session.cookie_path = /tmp session.cookie_domain = my server's internal URL (should I even set this? this field was blank before, but not commented out) session.referer_check = Off I ran the following to ensure that the fold...
