storage

Today FreeBSD operating system turns 26 years old. 19 June is an International FreeBSD Day. This is why I got something special today :) FreeBSD Enterprise 1 PB Storage https://vermaden.wordpress.com/2019/06/19/freebsd-enterprise-1-pb-storage/ #verblog #backup #beadm #enterprise #freebsd...

So I'm reading about ZFS on the FreeBSD ZFS quick-start guide, and I'm stuck at this part: when I attempt to use a device (/dev/da0), it throws an error and the device dissapears until I reboot. :\ Specifically, this: zpool create example/ dev/da0, and throws the error: cannot open '/dev/da0'...

Hi guys! :3 I was wondering about something... I tried installing 12.0 (and failed once again) to replace Xubuntu on the notorious ASUS X205TA. :( But I still want to use ZFS. Were it not for wanting ZFS, this thread would be elsewhere Online. :) I know how to install it, but my question is...

I'm writing a simple hook to open / openat. Like this static int openat_hook(struct thread *td, register struct openat_args *uap) { // print uprintf(" SYS_openat: \"%s\", flags: %d, mode: %X fd: %d\n", uap->path, uap->flag, uap->mode, uap->fd); get_whole_addr(td, uap); return...

As we're running out of disk space, I've added another block storage device and made it a zfs partition with gpart : $ gpart show => 40 125829040 vtbd0 GPT (60G) 40 1024 1 freebsd-boot (512K) 1064 6291456 2 freebsd-zfs (3.0G) 6292520...

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 searched google and this forum but still no sucess. I've created a file-backed filesystem (memory disk). what I want is to automatically mount the md device at boot. What would be the correct entries in the rc.conf and fstab. Thank you for your inputs.

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?

Hello, guys! I'm looking for solution. We have a storage with 60x4TB zfs pool wich split on three raidz2 arrays + 256 Gb RAM. We have to connect around 30 Mac OS clients for online video streaming (~7-8Gbits/sec) via NFSv3 Some times we have a users complain about freezing. Our configuration...

Hi there :) Someone has demonstrated for a while running OpenStack hosted on FreeBSD 11. Described right here For me that sounds awesome. I would like to have a similar setup now with FreeBSD 11 XEN and hosting OpenStack on Dom0. The minimum goal is to run FreeBSD as an Nova Compute Running...

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...
