I created a zpool and two ZFS volumes in OpenSolaris. I would like both ZFS volumes to be exportable. However, I don't know how to set that up.
These are the steps I did:
1) Create the zpool using raidz1 across five disks.

Hey all,
I have a machine with 16 drive slots. Two of the drives have a ZFS mirror of the operating system, the other 14 contain the storage raidz.
So, after installing Opensolaris on the OS drives, how can I remount the storage raid?

Hi Folks,
Looking for info here more than any actual HowTo, does anyone know if there is an actual way of converting a Veritas or UFS filesystem to ZFS leaving the resident data intact.

Hi guys!
How come ZFS is said to be not just a filesystem but a hybrid filesystem and also a volume manager? Please explain.
I will appreciate your replies. Hope you can help me figure this out.
Thanks in advance! (1 Reply)

Need to ask the question regarding extending the zfs storage file system.

I have a esxi 6.7 server running a Solaris 10 x86 vm (actually a bunch of them). The VM uses zfs for the pools (of course). I expand the underlying ESX logical disk, for example from 50GB to 100gb, then I set autoexpand=on <pool> that belongs to the esx logical disk.

drv_usecwait
drv_usecwait(9F) Kernel Functions for Drivers drv_usecwait(9F)
NAME
drv_usecwait - busy-wait for specified interval
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
void drv_usecwait(clock_t microsecs);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
microsecs The number of microseconds to busy-wait.
DESCRIPTION
drv_usecwait() gives drivers a means of busy-waiting for a specified microsecond count. The amount of time spent busy-waiting may be
greater than the microsecond count but will minimally be the number of microseconds specified.
delay(9F) can be used by a driver to delay for a specified number of system ticks, but it has two limitations. First, the granularity of
the wait time is limited to one clock tick, which may be more time than is needed for the delay. Second, delay(9F) may only be invoked
from user context and hence cannot be used at interrupt time or system initialization.
Often, drivers need to delay for only a few microseconds, waiting for a write to a device register to be picked up by the device. In this
case, even in user context, delay(9F) produces too long a wait period.
CONTEXT
drv_usecwait() can be called from user or interrupt context.
SEE ALSO
delay(9F), timeout(9F), untimeout(9F)
Writing Device Drivers
NOTES
The driver wastes processor time by making this call since drv_usecwait() does not block but simply busy-waits. The driver should only make
calls to drv_usecwait() as needed, and only for as much time as needed. drv_usecwait() does not mask out interrupts.
