Hi All,
I am new to solaris. Please clarify me on the following questions.
1) On Linux to know the presence of ext2/ext3 file systems on a
device we use tune2fs command. Similar to tune2fs command is there
any command to know the presence of ZFS file system on a device ?
"zpool import" will list any zpools even when they're not currently
visible in a "zpool list"
"zfs get -r all zpool-name" will list all zfs filesystems
2) When a device is shared between two machines , What our project
does is,
-> Create ext2 file system on device
a) Mount the device on machine 1
b) Write data on the device
c) unmount the device from machine 1
d)mount the device on machine 2
e) read the data on the device
f) compare the current read data with previous write data and
report the result
g) unmount the device from machine 2
h) Goto step a.
Like this , Can We share zfs file system between two machines. If
so please explain it.
It's always going from machine 1 to machine 2?
zfs send [EMAIL PROTECTED] | ssh [EMAIL PROTECTED] | zfs
recv filesystem-one-machine2
will stream a snapshot from the first machine to a filesystem/device/
snapshot on machine2
3) Can we create ZFS pools (or ZFS file system ) on VxVm volumes ?
if so, how ?
It's been so long since I've cared about VxVm volumes, I don't know.
4) Can we share ZFS pools ( ZFS file ststem ) between two machines ?
Yes but what are the requirements here?
5) Like fsck command on Linux, is there any command to check the
consistency of the ZFS file system ?
ZFS is a transactional, copy-on-write filesystem. It's always
consistent.
There is an output for zpool status that includes this information,
for example
[strongspace12(zone):/] root# zpool status
pool: thumper12
state: ONLINE
scrub: none requested
