hmmm
i have three sata SSDs that i want to use for my server's rootfs

do i do

• Btrfs on top of LVM RAID5
• ZFS (RAIDZ1)

i would love to just run Btrfs-native RAID5, but apparently that's still utterly broken, grr

@deneb Are they consumer SSDs or more entetptise-y ones?

@snep consumer
different models, all 250GB TLC with DRAM cache

@deneb Hmm, there are split opinions about if ZFS wears consumer SSDs more quickly or is more error prone without capactior backed SSDs in case of power outages, though the general consensus seems to lean more towards "don't use ZFS on consumer SSDs for longevity"

@snep huh, good to know, i wasn't aware
but i have to wonder why
cause e.g. if it's about CoW then wouldn't that put Btrfs in the same boat?
i guess i'll look further into it

@deneb For CoW I'm sure BTRFS would be in the same boat (or so I assume), though the average write operations are said to be a lot more frequent and consistent on ZFS which wears the cells out faster. Truth be told, though, I've not used ZFS much personally, I'm more of a BTRFS kinda guy myself, so take all that with a grain of salt. I just thought I'd mention it because it keeps coming up in server storage discussions as a warning and discussion point ^^

@snep yeah that does helps, ty ^^
i haven't used ZFS at all yet, was just wondering if it might be worth it, esp since it is a bit of a hassle on arch

@deneb Do you really need RAID5? I'd vote for btrfs on two disks with native mirroring.

@rw that's kind of what i'm doing already — two of the drives in question are holding my important(-ish) data, but not the rootfs

i added the third disk recently and am not sure how else to use it; the extra space would be very handy

the system currently boots from a single cacheless 500GB SSD, which i'd really love to give a less important job to
