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, you’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. Couldn’t get into my share, and my password wouldn’t work. I found that you can test your PAM mapping like so: smbutil login –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 […]
