Comments:
<0> Blis***, SpyderMan : It does, however, allow you to have more than one drive failure
<1> is there a way of forcing dpkg more than with --force-all`
<2> Blis***: agreed - and to be honest I'd probably go for it if I was re-engineering from scratch. In the mean time with over 100 servers and 5 years, practically all the big downtime is controller failures not multiple disk (TBH can't think of one multiple disk failure, but my meory ain't what it used to be....)
<1> ?
<3> js_: don't know.. hardware raid isn't initialized i guess... worked before with Sarge
<1> i can't load my browser, i can't go back and forth with the problem
<1> i don't know if my system will boot the next time
<3> js_: but with the install cd kernel it "just works"
<1> (or give a gui, if it does)
<4> pipeline: but RAID-6 is just RAID5 with some more redundancy. The cost during array rebuild is still huge.
<1> i'm slightly nervous
<5> mon: it worked before what?
<3> js_: before i reinstalled
<0> Blis***: Yes. It's even more huge. But that's OK.
<3> js_: not sure what i did then to make it work... if anything
<4> pipeline: also, suppose you have a 4+2 drive RAID-6, and compare the cost and speed/resilience with a 2+2+2+2 RAID10
<0> Blis***: Rebuilding the array is still faster than restoring from backup :P
<0> Blis***: Heh, the problem with RAID-1 is electrical costs.
<5> mon: do you use real hardware raid?
<4> pipeline: but the time to rebuild has a big big issue: while rebuilding, the array is very vulnerable...
<0> Blis***: It's the same reason you're starting to see big boxes of IDE disks in datacenters, and the rise of 73+ GB SCSI drives. Nobody wants to pay the electrical bill for 9G, full-height drives
<3> js_: yeah compaq: sym53c8xx
<4> pipeline: there are now 2.5" drive RAID p;roducts...
<2> pipeline: TBH if you want more than RAID5 or 10 you should probably look at SANs anyway - which offer all sorts of interesting choices for handling failure
