I received this error message when I started my virtual machine and tried to logon to my database as sysdba to startup the instance.
[oracle@node1 ~]$ sqlplus / as sysdba

ERROR:
ORA-09925: Unable to create audit trail file
Linux Error: 30: Read-only file system
Additional information: 9925
ORA-09925: Unable to create audit trail file
Linux Error: 30: Read-only file system
Additional information: 9925

- I rebooted my machine and got following messages which pointed to some errors encountered during filesystem check and instructed to run fsck manually.

[root@node1 ~]# init 6

Checking filesystems

/: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
*** An error occurred during the filesystem check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue):

– I entered password for root to initiate filesystem check. As a result I was prompted multiple no. of times to allow fixing of  various filesystem errors.

(Repair filesystem) 1 # fsck
Fix(y)?

- After all the errors had been fixed, filesystem check was restarted

Restarting e2fsck from the beginning...

/: ***** FILE SYSTEM WAS MODIFIED *****
/: ***** REBOOT LINUX *****

- After filesystem had been finally checked to be correct, I exited for reboot to continue.

(Repair filesystem) 2 # exit

– After the reboot, I could successfully connect to my database as sysdba .

[oracle@node1 ~]$ sqlplus / as sysdba
