It's a very slow process and I can only do it with your valuable helps.

You are not compressing anything in the described procedure.
Creating an intermediary file (hostname_rpool@001.snapshot1) is an unnecessary step, you could (and should) directly pipe the "zfs send" command to a "zfs receive" one.
You are destroying your USB file system by creating a zfs pool on the very same device. Assuming you have no free partition on your USB disk, You need to create a file based pool.
There are also specific options you need to use to import a root pool as otherwise, some of the properties, especially mount points, will collide with your current root pool.

This is still going after running for more than 4hrs. My understanding is that this step will transfer a snapshot of all the data from local rpool & their datasets to backups zpool on USB drive. Is this correct? However, my intention has always been to create a snapshot of local rpool recursively into a single file with the following command:
Is this command correct and how to include compression in the process as well? Also, how to list toc of /export/home/hostname_rpool@001.zdump after successful creation?
Thanks so much again,
George

This is dubious, as I already wrote, you need specific options to import a root pool, at least a different root mountpoint.

There are many factors that might affect the performance of such a command.

Yes, but I suspect there will be errors because you'll end up with multiple file systems with the same mount point.

No. If you want to create a file, just redirect zfs send to it. This is what the link to the documentation I posted does.

You might just pipe through gzip.

There is no way I'm aware of to list the content of such a datastream, moreover, as it usually contains volumes and snapshot, it won't be as stratforward as with a tar or cpio of ufsdump.
The only way to make sure a stored datastream is valid and list the files it contains is to extract (receive) it somewhere.
I tried to boot up the local Solaris 10 x86 operating system instead of from installation disk all along but encountered the following error:
Code:
cannot mount ‘/export’: directory is not empty
svc:/system/filesystem/local:default:WARNING:/usr/sbin/zfs mount –a failed: exit status 1
Nov 15 10:50:17 svc.startd[10]:svc:/system/filesystem/local: default: Method “/lib/svc/method/fs-local” failed with exit status 95.
svc.startd[10]: system/filesystem/local: default failed fatally: transitioned to maintenance
The bootup process is running ‘zfs mount –a’ which generates the same error when running it manually (cannot mount ‘/export’: directory is not empty), but I don’t know which table (/etc/.../*tab?) that it is looking up to get ‘/export’ and yet I can see this filesystem has already been mounted using ‘df –h’ as follows:
So I don’t understand where the issue is with mount /export which is preventing the system from booting into multi-user mode.
Not only have I not being able to create a zfs snapshot but appears to have disturbed possibly original mount point of local rpool as well.
Any idea on what to do?
Once again, I can only fix this issue with your persistent urgent advice.
Also, can I continue to generate zfs snapshot with zfs send -R -p rpool@001 > /mnt/usbdrive/hostname_rpool@001 once the system is running in multi-user mode? ie rpool is mounted.
Thanks in advance,
George

I have noticed that when I copy files to flash disk and in UI I see message copy completed in notification area on task bar, usually copy is not completed. So, if I eject the media I loose data.
