Extend root file system with hfs FStype

[Gabriel_23]

I am currently supporting a server running 10.20. I need to extend the root file system. How can I extend root using the fsadm command (I assume this is the easiest way). First of all when I issue "bdf", /dev/root is shown instead of /dev/vg00/lvol3, but /dev/vg00/lvol3 shows up in /etc/fstab. In addition, the FStype for root is hfs. Also, not sure what patch is linked to OnlineJFS. Please help if possible...Thx

The /dev/root is almost certainly an artifact of using LVM maintenance mode. Mv /etc/lvmtab /etc/lvmtab.sav and do a vgscan to fix that problem. You should then shutdown and reboot to be safe. Now for the bad news: /, /stand, and primary swap MUST be contiguous LVOL's -- for all practical purposes, you can't expand / 'in place'. The method for doing this is to use IgniteUX to make a 'make_tape_recovery' tape and then Ignite the system. You are given a chance to resize LVOL's/filesystems during the Ignite process.

Hi,

Are u in multiuser mode and issuing bdf command ? I have faced similar problem. u have to just rename /etc/mnttab and run the mount (without any option) and bdf command.

Also, OnlineJFS is only for extending JFS file systems. HFS file systems cannot be extended without unmounting that too /stand,/ & swap should be contiguous.

Thanks,

Sundar.
