Hi Friends! I'm built a ZFS+Samba+ACL+AD scheme for using at work. All works, but I'm found that maximum ACL entries on FS item are 127. Since my scheme uses final AD-users, not groups - I see that this limit can be theoretically a problem for me. So can this maximum be extended? And if not...

Greetings. I have few jails running nginx on my FreeBSD 13.1 host. I'd like to create another jail for their SQL database needs. I'd like to create ZFS dataset for this purpose (for MySQL jail) but should I create it on host? If the dataset is created within the host, could the Jail access it...

Greetings. Nginx states (Changes with nginx 1.21.5 - 28 Dec 2021): Change: now nginx always uses sendfile(SF_NODISKIO) on FreeBSD. So it seems, it uses "sendfile: on;" by the default on FreeBSD. Afaik, sendfile should be off for FreeBSD and ZFS, to avoid redundant data caching. I'm on ZFS...

Hi I recently decided to move my FreeBSD installation onto a new drive. Since I was using ZFS, I achieved this by inserting the new drive, and then using the memstick installer on a USB drive to perform a basic install. After this I dropped to a shell, unmounted all the destination datasets...

When we encrypt the ZFS disk (whole volume), we need to enter a "passphrase". However, a "master key" is created to encrypt the data. The "passphrase" is the key to unlock the "master key". So, we can change the "passphrase" later and the "master key" remains the same but will be secured by the...
