Power supplies are a relatively cheap upgrade.

hi

8 1.8TB drives in raid 10 is theoretical capacity of 7200gb but actually 6700, then with ufs formatted it's 6500. there any online calculators to get these real numbers from different raid levels? only online raid calculators i found just give theoretical capacity but that's pretty useless

for a start, drive manufs use misleading descriptions of size

LIARS

i got an old server for homelab learning. it has 8 disks in it. i set up raid 10 and got 6,700GB raid formatted, then 6,500 usable in freebsd + ufs. then i just changed raid level to raid 5 + 1 hot spare, raid formatted was like 10,000GB. went to do freebsd install and after i selected ufs and gpt installer said invalid size argument. 14.2 btw. is

that expected?

then you have some overhead for raid, possibly - eg. a dirty-map (which could depend on a config granularity)

then you have filesystem overheads, fs-type dependent and possibly config dependent

in short, there's too many variables

ya that's why i'm resorting to installing freebsd + ufs on all of the different raid levels. know why i got that error?

not me, sorry

weird. changed raid level to 5 with no hot spare and installer worked lol

what's the right way to view how much usable disk space i have in ufs in GB?

df -h or?

Yes, that

size 11T, used 1.6G, avail 9.8T (???)

ok, so trying to do freebsd-update with boot environments and bectl, i've read 2 docs that suggest creating a new BE then mount+chroot or jail into it to do the update, and a different klarna article that suggests mounting the new BE and using freebsd-update and specifying the mount path

which would be cleaner?

I'd do the latter

yeah, the mount of devfs and jail parameters made me nervous there's some implied logic going on

when the fuck will Github add support for FreeBSD in their CI/CD stack @#!

and since i have to update the EFI loaders manually anyway, it should be a wash

i just want to prep the upgrade and reboot into it using BE's

vkarlsen: oh! one difference is with the jail the third install command can be run, where klarna says after reboot do the third install

frankly, the upgrade portion of the handbook is quite unclear about the series of tasks to do :P

does freebsd-install need devfs mounted?

er, freebsd-update install

mage: probably never. and also, why

Demosthenex: if you're updating from outside a jail, doubtful

rtprio: i'm trying to upgrade inside a new boot environment, mounted with bectl jail

then probably don't need devfs, but what can it hurt, really

i just tried the upgrade using a jail, need to do the final reboot

seemed to work. install said nothing left to do, and the pkg upgrades worked too

only 1 port to recompile after
