filesystem swap

Nobody's Hero — Thu, 22 Sep 2005 09:15:36 GMT

I created some filesystem swap.
What are the files in this are for?
Will they be cleaned up after a reboot?
Should I clean up the file manually?

Robert,

I've never used FS swap but I'm surprised that you're seeing files in there. What files? I can see where there might be a lost+found or something.

I suppose it's possible, maybe even probable, that when you swap to it, the pages are actually written out to files. What do the file names look like?

NO. You absolutely do NOT want to delete any files in the filesystem swap area. These files are used by HP-UX. Don't worry about them and leave them be.

Normally, filesystem swap is for temporary usage because performance is quite a bit slower than a raw lvol. It is a filesystem so all the files can be manipulated just like any other filesystem. There is one exception: /mntpoint/paging is a directory placed into the filesystem to handle paging (swap). That directory must remain untouched. Once swap has been added (raw or filesystem), it CANNOT be removed until a reboot occurs.
