Recently I ran into a problem booting my root ZFS mirror. Couldn’t get it to load, and only saw blinking cursor or blank screens. Grub could see the FS though! Â I suspect I had a corrupted or out-of-sync zpool.cache file. Don’t ask me how that can happen, because the whole […]
Just ran into this quick blurb… zfs set com.sun:auto-snapshot=false butank/DATA/backups So I have backups running to a secondary storage ZFS pool in my server and today I realized my disk space was consumed by ZFS snapshots. Â I thought, there’s no way even my backups are using that much data, even […]
I finally did some reading, and found that setting my vfs.zfs.arc_max to about one-half my RAM, minus 512MB, and setting vm.kmem_size to 1.5x my RAM, it would stop giving me the kmem_map panic.
Here’s my notes for ZFS root installation with FreeBSD 8.1. (amd64 on my system) Boot up the FreeBSD install disk, youâ€™ll need one with the Fixit system. In the examples listed, I had 2 disks, ad4 and ad6. Yours may be different, replace as necessary. 1. Add the modules on […]
I setup my share right, followed all the instructions, set the /etc/pam.conf entry. Couldnâ€™t get into my share, and my password wouldnâ€™t work. I found that you can test your PAM mapping like so: smbutil login â€“c username But that gave me: Keychain entry not found. Ok, had to […]
Just a few quick notes on the ZFS CIFS sharing. Check the /etc/pam.conf has the smb line: other password required pam_smb_passwd.so.1 nowarn If not, add that to the end of the file. If you, check /var/smb/smbpasswd you should also see a line for your account with a hashed password listed. […]
Notes to self: Install your system to a PARTITION, NOT the whole drive. Â I seem to remember reading somewhere that this was required. My system had 2 disks. Â rpool was setup on disk 0. Â (those are ZERO’s not O’s.) c8t0d0s0 Â (disk 0 with rpool) c8t1d0s0 Â (disk 1 we want […]
This is just another one of those things that didn’t make any sense and only partially does now. At least NOW I know there is more at play here than the simple solutions in Samba using create mask and create directory mask. In Linux, that’s how I would get around […]
