Resizing /usr

hitchup · #1 December 22nd, 2009, 00:56

Portupgrades have left my system bumping up against the limit of space in /usr. I am running freeBSD as a virtual box guest. I have virtual box set to auto resize however, that doesn't increase the size of /usr.

How can i increase the size of /usr? I have read several posts and am still not sure how to continue.

Check growfs(8).

Move /usr/ports to it's own filesystem (with lots of room).

I second SD's suggestion...

or move /usr/local, & symlink /usr/ports to /usr/local/ports.

of course with a virtual machine it shouldn't be a huge deal to mount a second virtual hard drive, make the new partitions the sizes you want, dump | restore to the new virtual drive (set up the boot code &cet obviously), & restart with the new virtual drive.

I have an additional 6+GB(unused) on drive ad0, I have unsucessfully tried to add slice s2 using sysinstall. It fails on Write in that ad0s1 is in use and can't be written to(i think). I desire to add this as an additional file system and assign it a mount point say /usr/local and then mkdir ports and move the contents of /usr/ports to it and then symlink to it from /usr/ports.

How do I add the slice so that it persists? Is my logic correct?

Thanks

Sounds fine, you need to do # sysctl kern.geom.debugflags=16 before you can edit the boot disk.

I goofed.

I added the new partition ad0s2d to fstab.

It is detecting an error. No Superblock found.

How can I recover? The file system comes up read only and I can't invoke any editors.

Standard procedure, see my signature

Code:

# fsck -y
# mount -u /
# mount -t ufs -a
# swapon -a

@SirDice
Thanks, File system rw and edited fstab.
fsck -u:

Code:

/dev/ados2d
Cannot find file system superblock
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: can't read disk label

Okay, How do make the label? And, make it persist?

Using bsdlabel(8) and reading the handbook (especially section 18.3.2.1).

And yes, be very careful with these commands, read their man pages, check the options used and make sure you're writing to the device you want.

hitchup · #12 December 24th, 2009, 15:59

No longer working on this. Starting over. Messed up the partition table.

Beastie · #13 December 24th, 2009, 19:53

Then you don't know partition tables can be edited entirely using # fdisk -u.
