Just to reduce my stress levels and to give the webmaster some useful info to help fix this broken forum: I tried posting a reply to the main thread for 'cp -r hanged copying a directory' and got the following error -- seems like it can't find the parent thread/message's id in the database at a

Keep getting Java exceptions posting to the proper thread for this -- just lost an hour --- WTF??? Had to reply to my own post as Max's reply (which I saw in my email inbox) has not appeared here. Again, what is wrong with this forum software -- it seems so buggy, or am I missing something here

Today my production server crashed 4 times. THIS IS NIGHTMARE! Self-healing file system?! For me ZFS is SELF-KILLING filesystem. I cannot fsck it, there's no such tool. I cannot scrub it, it crashes 30-40 minutes after scrub starts. I cannot use it, it crashes a number of times every day! And wi

Hi Max, I re-ran the cp command and when it hanged I ran 'ps -el' looked up the cp command, got it's PID and then ran: # truss -p PID_of_cp and it output nothing at all -- i.e. it hanged too -- just showing a flashing cursor. The system is still operational as I am typing into the browser. B

Are there any updated guides/blogs on how to configure ZFS boot on a build 88 or later system? If I already have an existing zpool, will I be able to just add a root/boot dataset or does the root/boot dataset have to have it's own pool? I have several working systems that have small UFS partiti
