During installation, the installation created default ZFS filesystems, like the dump and swap locations.
I want to change the blocksize of the /dump and /swap locations and make them ZFS volumes.
The ZFS system is on a zpool called rpool
I was able to do a zfs destroy on /rpool/dump and then create another dump location with the proper options: zfs create -b 131072 -V 1024m rpool/dump
I cannot destroy /rpool/swap though. It tells me that the ...dataset is busy. I did some investigating and found that I have to do a dumpadm but that doesn't work either:
>dumpadm -d swap
dumpadm: no swap devices could be configured as the dump device
How can I destroy the /rpool/swap directory and then create another swap directory and make it a volume with a particular blocksize? Do I rename the swap location to something else?
Hello,
I have given 3 x 1 TB LUNs to add more swap space in a Solaris 11.3 OS
-bash-4.4# swap -l
swapfile dev swaplo blocks free

I have a 240GB disk as rpool. I have installed Solaris 11.3 to a partition which is 110GB. Now I have another 130GB which is unallocated. I want to use that additional space as a temporary folder to be shared between Solaris and Linux. The additional space had no /dev/dsk/c2t4... entry so I used... (8 Replies)
I am trying to test simple zfs functionality on a FreeBSD 8.2 VM. When I try to run a 'zpool create' I receive the following error:

Hello,
To learn ZFS, i try to create pool .
and for that i want create 10 files with 512MB (because i dont have multiple disks and multiple controllers)
ADMIT THAT THIS IS TEN HIGH-PERFORMANCE HARD DRIVES
To get this 10 files,all of them have the same size : 512MB,
I do these... (9 Replies)
Hi All,
I am using this commands to dynamically increase ZFS swap space on Solaris
my question is:
1- after i make these commands it will permanent or it will remove after restart
2- how to make it permanent

I'm trying to write a script that in the end will from one central location hop to a bunch of servers and then run a series of ping tests. The thing is, the list of devices that needs to be pinged is going to be different for each server. So what I want to do is be able to do is read through the... (0 Replies)
swapmem_on(5) OBSOLETE swapmem_on(5)NAME
swapmem_on - OBSOLETE kernel tunable parameter
DESCRIPTION
The tunable is obsolete. Processes will always be allowed to use pseudo-swap space if it is available.
In previous versions of HP-UX, system configuration required sufficient physical swap space for the maximum possible number of processes on
the system. This is because HP-UX reserves swap space for a process when it is created, to ensure that a running process never needs to be
killed due to insufficient swap.
This was difficult, however, for systems needing gigabytes of swap space with gigabytes of physical memory, and those with workloads where
the entire load would always be in core. This tunable was created to allow system swap space to be less than core memory. To accomplish
this, a portion of physical memory is set aside as "pseudo-swap" space. While actual swap space is still available, processes still
reserve all the swap they will need at fork or execute time from the physical device or file system swap. Once this swap is completely
used, new processes do not reserve swap, and each page which would have been swapped to the physical device or file system is instead
locked in memory and counted as part of the pseudo-swap space.
WARNINGS
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
