| lteo | if i want to reinstall my VPS with a different version of OpenBSD using the bsd.rd method using the "SSH to serial" method, would i need to prepare a bsd.rd that can output to serial console? or will a stock bsd.rd work? | [08:57] | |
| toddf | heh you're obviously not realizing what points things to the console of com0
boot.conf aka /boot and boot blocks in general do this for you, all kernels have the capability to do serial console | [09:07] | |
| lteo | toddf: cool, thanks. so basically i can just use the stock bsd.rd and it will do the right thing | [09:13] | |
| toddf | youbetcha, if you see a boot> prompt on serial, 'boot bsd.rd' will do what you want | [09:14] | |
| lteo | toddf: i totally get it now. since a reboot of the VPS would get it into serial anyway, i will be able to access the boot prompt via serial, so i can boot bsd.rd from there
funny thing is, i have done this hundreds of times on pyhsical boxes, but somehow this "SSH into the VPS serial console" concept threw me off for a moment :D toddf: thank you | [09:16] | |

| ballen | wouldn't IOP be double on 8x RAIDZ | [18:55] | |
| pilgrimd | 4x8 Z2 will provide n+2 for any two disks. 8x4 Z1 is only partially n+2. | [18:56] | |
| ballen | as a raid set can only do one operation at a time | [18:56] | |
| pilgrimd | That's 36 disks, not 32. | [18:57] | |
| ballen | two os drives, two spare
and two 32GB Intel X25-E mirrored for ZIL | [18:58] | |
| pilgrimd | I'm pretty sure ZFS can do parallel operations on a single vdev.
If it were me, I would configure it as 4x8-disk Z2, making sure to put two disks on each controller. | [19:01] | |
| ballen | hmm, once I get the hardware I'll have to benchmark it
yep | [19:02] | |
| pilgrimd | I think the other factors are a a wash at that point and that configuration gets you minimum n+2. | [19:03] | |
| ballen | right | [19:03] | |
| *** | fink has quit IRC (Quit: fink) | [19:03] | |
| pilgrimd | With 32 spindles, n+2 is would be more important to me. :)
s/ is// Which OS, btw? | [19:03] | |
| ballen | Nexenta Core
I'll install Solaris 11 to see if its anywhere any better* | [19:04] | |
| pilgrimd | We have a file server at work running that.
It's wonky. | [19:05] | |
| ballen | so n+2 with RAIDZ2 is good, but its not doubling risk to goto RAIDZ in this case
due to faster rebuild time and > number of raid sets how so wonky? | [19:06] | |
| pilgrimd | Maybe, but IMO n+2 and t(rebuild) = 2m >> n+1 and t(rebuild) = m | [19:06] | |
| ballen | well depends on what the actual difference in rebuild time is | [19:07] | |
| pilgrimd | If you just do things how Nexenta wants you to do them, it works ok, but we tend to demand more than that from the servers.
We have to drop to their "shell" to do most of the volume and iSCSI, NFS and CIFS server configuration bits | [19:07] | |
| ballen | yea I'm not going to use their appliance OS
but core | [19:08] | |
| pilgrimd | Ah. | [19:08] | |
| ballen | which doesn't have their CLI
or gui nor the TB limit on the free version | [19:08] | |
| pilgrimd | Ours isn't the free version. :) | [19:09] | |
| ballen | indeed
Yea the plan it to play with Gluster on top of this and see how well it would work to create a unified name space of multiple units | [19:09] | |
| pilgrimd | The NexentaStor box has been problematic. We're close to saying to hell with it and reloading the thing straight-up Solaris. | [19:11] | |
| ballen | Has Oracle change the licensing on Solaris
changed* | [19:11] | |
| pilgrimd | Just some pesky bits about the support contract being voided. | [19:11] | |
| ballen | at some point it was you could only trial it for 90 days on non-Sun hardware without a Solaris support contract | [19:12] | |

| mattx86 | the support.arpnetworks.com site is basically the same as e-mail support@, correct?
emailing* | [21:05] | |
| ix33 | last time i emailed, garry opened a ticket for all further correspondance | [21:06] | |
| mattx86 | hm.. cuz last time (been a little while), I couldn't get an e-mail to him due to some configuration error on my e-mail provider's part
meh, I'll just open a ticket :) | [21:08] | |
