If so, then in addition to one of Colin's suggestions [1] you might be
able to get more details of what happened, as described by

https://serverfault.com/questions/962292/centos-zsh-locking-failed-for-root-zsh-history-read-only-file-system-readin/962319#962319

"[snip] When your root file-system encounters such an error, most of the
time the error won't be recorded in your log-files, as they will now be
read-only too. Fortunately since it is a kernel action the original
error message is recorded in memory first, in the kernel ring buffer.
Unless already flushed from memory you can display the contents of the
ring buffer with the dmesg command. [snip]"
