Re: file system question

Shalom,

This would indicate a file system has problems and is now mounted read only. This will prevent significant database rights.

Take a look at /etc/mtab

For information on mount

Re: file system question

I know nothing, and "linux OS" is not a
particularly precise description of the OS
here, but some operating systems will disable
write access to a file system if there the
associated disk hardware logs many errors.

Could be a hardware problem. Have you looked
for hardware errors in the system log
file(s)?

Shalom,

This is likely the result of a hardware problem.

I would not necessarily trust this disk(array?) and would take a cold backup as soon as possible.

Re: file system question

As pointed out already Linux will mount file systems read-only when it detects disk errors, in order to prevent your data going completely fubar.

It could be as simple as some file system inconsistencies in need of a fsck, but I would take a backup as soon as possible just in case.
