comment ZFS: Trying to remove top-level drive from Zpool
@chronic I wonder what documentation you read. Increasing zpool size is just a matter of adding a disk or even a new stripe/mirror/raidz to it. The only trick in some cases is that you need to perform a zpool set autoexpand=on after adding the disks. Same goes to extend space on a single device zpool, resize underlying this, autoexpand=on and then off and new space is available.

comment zfs replication temporary file
that's manual work, but on the destination you can do zfs list -t snapshot and check how much space is use.

comment zfs replication temporary file
I add a similar situation recently, but you can't see anything besides the destination increasing. In my case was send and receive . But even using -v option, only at the end of the operation it tells you how long it took and the amount of data.

can you explain why is not correct? with the current implementation after a max of 5 "failed" executions it ends.

comment How can I do NFSv4 UID mapping across systems with UID mismatches?
From find man: -group gname True if the file belongs to the group gname. If gname is numeric and does not appear in the group(4) database, it is taken as a group ID.

comment Virtualbox 4.2.18 Ubuntu guest — unable to access shared folder
that might be a know bug. try to use the cli and copy the file using the full path. ex: cp /sf_mount/file /home/my_user. If it works it is because of a bug with kernel 3.10 and up if I remember correctly.

have you tried the escape sequence to terminate the connection? the default is "~.", usually this forcibly closes the connection.

comment useradd does not work but has exit code 0
you're not running the command as root. at least the root prompt normally is # instead of $. Also, when you do passwd you get permission denied.

comment How to set up an SSD as a cache for the big Hard Drive?
you have to patch due to your kernel version. centos is on 2.6 while the main version now is 3.x. you can check the change log of centos kernel and verify if they added the solutions provided or if you have to patch your kernel.

comment Create Zip for each subfolder but containing only matched files
Updated the question. This should work but if a directory does not have any match for the filesnames it will throw a error / info stating "nothing to do", so no zip file will be created anyway.

comment How to unpack a downloaded tar.bz2 archive?
clearly you are not aware of how to navigate in linux. Check this links: linuxcommand.org/lts0020.php and en.wikibooks.org/wiki/Linux_For_Newbies/Command_Line. They will help you understand how to navigate in the command line.

comment Samba 2.2.12 accepts my password, but is rejecting other user accounts?
also check your share policy in the clients and compare with the working one: Local Computer - Policy->Computer Configuration->Windows Settings->Security Settings->Local Policies->Security Options, the value Microsoft network client: Digitally sign communications. I believe that in the working one this might be disable and in the non working set as always. Give it a try.

What is the config of the share? Can we see it? Also are all the clients the same I mean Windows 7 systems?
