Disk full: increasing a volume (NO LVM)
Get into work to find that my /sybase volume is full at 100%. I can't even go in it to clean it up either!
Now, normally, I would just increase the LV or something! But this time, the ones that built this box had just assigned a full 25Gb lun straight to it!
File-System Mbytes Used Avail %Used Mounted on
/dev/disk/disk23 25.8g 23.2g 65 100% /sybase
And even stranger, among all of our other Sybase / HPUX servers, that's the only one using a HFS filesystem!
I've asked the storage to first increase the size of the lun... (MSA1000), but I'll still need to increase the FS, no?
Can anyone tell me how this is done?
I've found this:
http://networktechnologist.com/tips-hpux-lvm.html
But I can't see the -b option in fsadm.. Is this the appropriate way?
Any guidance would be appreciated.
Thanks!! Pat

Re: Disk full: increasing a volume (NO LVM)
Usual behavior would be:
lvextend
umount
extendfs
I'm not sure about hfs but on vxfs you need at least 1% free space, so this could cause trouble.

Re: Disk full: increasing a volume (NO LVM)
As the file system is HFS you will need to unmount it first before you will be able to extend it.
Also as it is at 100% capacity it my be prudent to temporarily free up some unused space first (mv/rm) within the file system before unmounting it and then move back the data after it has been successfully extended otherwise the extendfs may abort due to the lack of space

Re: Disk full: increasing a volume (NO LVM)
Yeah, I've seen increasing LVs and such failed sue to lack of free space...
My problem is that I can't even access it! I get I/O Errors when trying to cd into it...
Think I'll need to reboot and then try it again... see if I can at least get in and free up some space...

Re: Disk full: increasing a volume (NO LVM)
As mentioned before, the extend could fail if you don't have free space.
On the other hand you should think about converting the filesystem to vxfs if it is wrong configured.
Please check if vxfsconvert(1M)is available on your box, otherwise a recreate and restore will be the only way for it.

Re: Disk full: increasing a volume (NO LVM)
newfs -F hfs /dev/rdisk/disk23
mount /dev/disk/disk23 /sybase
as the disk does not belong to a particular volume group - no lvm as mentioned.
File-System Mbytes Used Avail %Used Mounted on
/dev/disk/disk23 25.8g 23.2g 65 100% /sybase
Not quite sure how this can be extended.

Mark

Re: Disk full: increasing a volume (NO LVM)
I'm just about to reboot the server and see if I can then access the volume to clean it up.

Re: Disk full: increasing a volume (NO LVM)
If you need to recreate please think about creating the new filesystem as vxfs using LVM, would make things a lot easier if you run in the same problem again.
