We had minor storage issues earlier that caused one storage node to take over for another. This is usually a successful operation that you wouldn't notice, but this time some client compute nodes did not reconnect to the storage for some reason. Some jobs may have died and we are working to figure out why that happened. Last Updated Thursday, Feb 12 04:17 pm 2026

Typographical Conventions

In what follows, we shall use the following typographical conventions:

Characters written in bold typewriter font indicate commands that may be typed and entered at the command line.
Characters written in italic typewriter font indicate non-specific filenames, directory names, or other arbitrary names.
Characters inserted within square brackets indicate individual physical keys to be pressed. For example, [Ctrl] indicates the "Control" key.
Text in blue indicates the output of a command or the contents of a file

So, for example,

$ ls somedirectory [Enter]

Means "at the bash prompt ($), type ls followed by the name of some directory, then press the key marked Enter."
Don't forget to press the [Enter] key as commands are not sent to the computer until this is done.

Important: Linux and bash are case-sensitve, so LS is not the same as ls. The same applies to filenames, so myfile.txt, MyFile.txt, and MYFILE.TXT are three seperate files. Be mindful of this when copying files to a PC, since DOS and Windows do not make this distinction.
