On an OmniOS server, I removed a single-disk pool I was using for testing.
Now, when I run zpool import it will show it as FAULTED, since that single disk not available anymore.

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)

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)

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)

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)

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 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)

THIN_METADATA_SIZE(8) System Manager's Manual THIN_METADATA_SIZE(8)
NAME
thin_metadata_size - thin provisioning metadata device/file size calculator.
SYNOPSIS
thin_metadata_size [options]
DESCRIPTION
thin_metadata_size calculates the size of the thin provisioning metadata based on the block size of the thin provisioned devices, the size
of the thin provisioning pool and the maximum number of all thin prisioned devices and snapshots. Because thin provisioning pools are
holding widely variable contents, this tool is needed to provide sensible initial default size.
-b, --block-size BLOCKSIZE[bskKmMgGtTpPeEzZyY]
Block size of thin provisioned devices in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors with-
out a block size unit specifier. Size/number option arguments can be followed by unit specifiers in short one character and long
form (eg. -b1m or -b1megabytes).
-s, --pool-size POOLSIZE[bskKmMgGtTpPeEzZyY]
Thin provisioning pool size in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors without a pool
size unit specifier.
-m, --max-thins #[bskKmMgGtTpPeEzZyY]
Maximum sum of all thin provisioned devices and snapshots. Unit identifier supported to allow for convenient entry of large quanti-
ties, eg. 1000000 = 1M. Default is absolute quantity without a number unit specifier.
-u, --unit {bskKmMgGtTpPeEzZyY}
Output unit specifier in units of bytes,sectors,kilobytes,kibibytes,... respectively. Default is in sectors without an output unit
specifier.
-n, --numeric-only [short|long]
Limit output to just the size number with the optional unit specifier character/string.
-h, --help
Print help and exit.
-V, --version
Output version information and exit.
EXAMPLES
Calculates the thin provisioning metadata device size for block size 64 kilobytes, pool size 1 terabytes and maximum number of thin provi-
sioned devices and snapshots of 1000 in units of sectors with long output:
thin_metadata_size -b64k -s1t -m1000
Or (using the long options instead) for block size 1 gigabyte, pool size 1 petabytes and maximum number of thin provisioned devices and
snapshots of 1 million with numeric only output in units of gigabytes:
thin_metadata_size --block-size=1g --pool-size=1p --max-thins=1M --unit=g --numeric-only
Same as before (1g,1p,1M,numeric-only) but with unit specifier character appended:
thin_metadata_size --block-size=1giga --pool-size=1petabytes --max-thins=1mebi --unit=g --numeric-only=short
Or with unit specifier string appended:
thin_metadata_size --block-size=1giga --pool-size=1petabytes --max-thins=1mebi --unit=g -nlong
DIAGNOSTICS
thin_metadata_size returns an exit code of 0 for success or 1 for error.
