I am running an opennms server that stores performance related data in RRDs. they are stored under /opt/opennms/share/rrd/*. As I start to track more and more nodes with more specific OIDs (snmp), disk io is starting to climb steadily. What I am looking to do is move /opt/opennms/share/rrd from openpool and mount it under storage pool (storage/onms/rrd). more specifically, i want to do something like this:
the problem here is i get:
So yes... the truth is there are plenty of directories beyond /opt/opennms/share/rrd/*. I'm just not sure how I can migrate this directory off openpool into storage.
Can anyone shed some light onto this. I am not 100% with zfs just yet but getting there
I was thinking about symbolic links but i'm not sure thats the best option here.
Hi all
I plan to install Solaris 10U6 on some SPARC server using ZFS as root pool, whereas I would like to keep the current setup done by VxVM:
- 2 internal disks: c0t0d0 and c0t1d0
- bootable root-volume (mirrored, both disks)
- 1 non-mirrored swap slice
- 1 non-mirrored slices for Live... (1 Reply)
I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)
Hi guys,
We had created a pool as follows:
zpool create filing_pool raidz c1t2d0 c1t3d0 ........
Due to some requirement, we need to destroy the pool and re-create another one. We wish to know now which disks have been included in the filing_pool, how do we list the disks used to create... (2 Replies)
I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity. (2 Replies)
Other than export/import, is there a cleaner way to rename a pool without unmounting de FS?
Something like, say "zpool rename a b"?
Thanks. (2 Replies)
installed Solaris 11 Express on my server machine a while ago. I created a Z2 RAID over five HDDs and created a few ZFS filesystems on it.
Once I (unintentionally) managed to fill the pool completely with data and (to my surprise) the filesystems stopped working - I could not read/delete any... (3 Replies)
I have a branded zone txdjintra that utilizes a pool named Pool_djintra that is no longer required. There is a 150 Gig Lun assigned to the pool that I need to reassign to another branded zone txpsrsrv07 with a pool named Pool_txpsrsrv07 on the same sun blade. What is the process to do this?

I accidently added a disk in different zpool instead of pool, where I want.

I have a newly created zpool, and I have set compression on, for the whole pool:
# zfs set compression=on newPool
Now I have zfs send | zfs receive lot of snapshots to my newPool, but the compression is gone. I was hoping that I would be able to send snapshots to the new pool (which is... (0 Replies)

RRDDUMP(1) rrdtool RRDDUMP(1)NAME
rrddump - dump the contents of an RRD to XML format
SYNOPSIS
rrdtool dump filename.rrd [filename.xml] [--header|-h {none,xsd,dtd}] [--no-header] [--daemon address] > filename.xml
DESCRIPTION
The dump function writes the contents of an RRD in human readable (?) XML format to a file or to stdout. This format can be read by
rrdrestore. Together they allow you to transfer your files from one computer architecture to another as well to manipulate the contents of
an RRD file in a somewhat more convenient manner.
filename.rrd
The name of the RRD you want to dump.
filename.xml
The (optional) filename that you want to write the XML output to. If not specified, the XML will be printed to stdout.
--header|-h {none,xsd,dtd}
By default RRDtool will add a dtd header to the xml file. Here you can customize this to and xsd header or no header at all.
--no-header
A shortcut for --header=none.
If you want to restore the dump with RRDtool 1.2 you should use the --no-header option since 1.2 can not deal with xml headers.
--daemon address
Address of the rrdcached daemon. If specified, a "flush" command is sent to the server before reading the RRD files. This allows
rrdtool to return fresh data even if the daemon is configured to cache values for a long time. For a list of accepted formats, see
the -l option in the rrdcached manual.
rrdtool dump --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd
EXAMPLES
To transfer an RRD between architectures, follow these steps:
1. On the same system where the RRD was created, use rrdtool dump to export the data to XML format.
2. Transfer the XML dump to the target system.
3. Run rrdtool restore to create a new RRD from the XML dump. See rrdrestore for details.
ENVIRONMENT VARIABLES
The following environment variables may be used to change the behavior of "rrdtool dump":
RRDCACHED_ADDRESS
If this environment variable is set it will have the same effect as specifying the "--daemon" option on the command line. If both are
present, the command line argument takes precedence.
