MOVE SWAP FILE FROM USB TO A LOCAL DISK ( EMBEDDED SYSTEM )

#1

Post by Transistor1 » 04 Jan 2019 23:24

Hi to all...
I recently installed latest version.. 11.2.0.4 - Omnius (revision 6315).. Clean installation of the embedded variant.
I came from an old version 9.2 Shigawire..

I followed the guide and a swap partition was created at my boot usb stick ( doesn't seem to have the option to place it at my HDD ), but afterwards i read that read - write operations might destroy it..

I created a swap file ( not partition ) at a local HDD..

My question is simple..

How can i discard the swap partition in usb stick and enable it at the swap file i created at my HDD?

Is it possible to make the system boot using the swap file? ( not the usb partition )

Thanks for any answer.. :)

Thanks a lot Snufkin!!!
I didn't notice these settings at all..
the system created a swap at /dev/md3 .. I guess it is at my HDD.
Is there a way to see where the /dev/md3, refers to?

/dev/md3 refers to the file i created, giving some commands manually
I named the file swap0..
Is this the file that is used now?
or i must delete it to gain the 2GB space?

I'm trying to create a swap file in 11.2.0.4.6400, but I cannot select a Mount Point:

My disks are in a ZFS pool and mounted.

Hi, your server already using native default Swap partition and is at 0% usage, between you need an UFS formatted disk to create a Swap file(non recommended), if this system uses an USB2.0, then swapping by with an USB3.0 at least may benefit, alternatively you can create a ZVOL to use as Swap device as a last resort.

However creating a Swap file on top of a filesystem may not be the best choice if performance/reliability if a concern, use a native Swap partition whenever possible if this system hits Swap constantly, in such case a small HDD/SSD is the best choice for performance and reliability.
