That's great; thanks Tomas and Erwan (and others who replied).

So, I'm seeing this:

root@shell:~# lsof +L1
COMMAND  PID  USER   FD   TYPE DEVICE SIZE/OFF NLINK   NODE NAME
mysqld  3164 mysql    4u   REG 254,16        0     0 589839
/tmp/ibvh7MKT (deleted)
mysqld  3164 mysql    5u   REG 254,16        0     0 589840
/tmp/ibT7D133 (deleted)
mysqld  3164 mysql    6u   REG 254,16        0     0 589845
/tmp/ibO9pgne (deleted)
mysqld  3164 mysql    7u   REG 254,16        0     0 589851
/tmp/ibOgMl6y (deleted)
mysqld  3164 mysql   11u   REG 254,16        0     0 589852
/tmp/ibON9JEJ (deleted)

My interpretation is that mysql has 5 deleted files of 0 size open which
are each taking up an inode. ls /tmp is empty.

I guess, if there were many (how many?) such entries, the disk would
appear full, if it ran out of  inodes.

Is that correct?
