Hi, I am a newbie to ZFS, but I've installed it on my laptop in order to learn about it (hey, it's a free country). I am totatlly confused about what are the recommended poudriere.conf settings to use? For example, there is the memory setting to use instead of TMPFS, but I configure TMPFS to...

I have a 8GB sd card in the pi3 and it ran out of disk space before it even came close to finishing. I thought 8GB would be plenty. Can someone recommend me the correct microSD card size?

...and no, this is not a long time ago in a galaxy far far away either... For those of you who are following my experience with FreeBSD and a hard disk failure, the is system install v2.0. If you are new to my little story, then you can catch up at the following links...

I have a machine with three 2TB drives mirroring the single zroot zpool. Is there a command sequence to pull one of those drives from the mirror, make the mirror forget it as a member of the pool and mark the drive as a spare rather than as an active pool member? A link to a page would be fine...

I've run 'tunefs -m 0' and 'tunefs -o space' on my UFS hard drive, however I haven't seen any reclaimed space. The changes wrote successfully. It's a 4TB drive so I expect 3.725 TB but I'm getting 3.52 TB. Any thoughts?

I am an idiot. I have no backup. Nothing critically important, but 6 TB of personal data I would sorely like to recover. I solemnly swear to create real backups first, before anything else, if I can get this working again. I'm a newbie to FreeBSD. This new FreeBSD system is replacing an old...

I am a relative noob to the storage world in general and FreeBSD in particular. OF what I have been learning of late, I have become somewhat familiar with such concepts like disk queuing, IOPs, latencies and the likes I am also reading the classic 'The design and implementation of the FreeBSD...

Hello guys, I'm working on the FreeBSD based dual-controller reliable storage system concept with aim to implement ZFS and in-memory cache. Fell free to discuss. The system is needed to be tested. So any help will be great!

Hi, as we all know there is no single command to show storage devices on FreeBSD system. Some grep the dmesg command, some check /var/run/dmesg.boot file, some try camcontrol command and so on ... as I struggle to create any empathy for Linux systems I really like the lsblk command and I always...

I want to know if FreeBSD / ZFS or UFS send a flag to lower level drivers regarding File System metadata in fashion similar to Linux where the ext3/4, jfs and other file systems use the REQ_RW_META and BIO_RW_META flags in struct request and struct bio structures respectively to tell lower...
