Full Discussion: Read Only Permission after the space is full.
Operating Systems Solaris Read Only Permission after the space is full. Post 302760025 by RudiC on Wednesday 23rd of January 2013 09:16:09 AM

Might work using the # mount -o remount,ro option, run from a cron entry or a shell loop. Make very sure nobody is using the file system when trying to remount, e.g. by grepping the output of lsof for it. Anyhow, this may not be sufficient, as e.g. editors open a file, read it, close it, and later try to overwrite it with the edited version - which then will fail, leaving users upset and helpless. Same is valid for applications running trying to update a logfile at intervals - they might fail and abort.
Me personally, I'm not feeling comfortable with that idea.

systemd-remount-fs.service

SYSTEMD-REMOUNT-FS.SERVICE(8)				    systemd-remount-fs.service				     SYSTEMD-REMOUNT-FS.SERVICE(8)

NAME

       systemd-remount-fs.service, systemd-remount-fs - Remount root and kernel file systems

SYNOPSIS

       systemd-remount-fs.service

       /lib/systemd/systemd-remount-fs

DESCRIPTION

       systemd-remount-fs.service is an early boot service that applies mount options listed in fstab(5) to the root file system, the /usr file
       system, and the kernel API file systems. This is required so that the mount options of these file systems -- which are pre-mounted by the
       kernel, the initial RAM disk, container environments or system manager code -- are updated to those listed in /etc/fstab. This service
       ignores normal file systems and only changes the root file system (i.e.	/), /usr and the virtual kernel API file systems such as /proc,
       /sys or /dev. This service executes no operation if /etc/fstab does not exist or lists no entries for the mentioned file systems.

       For a longer discussion of kernel API file systems see API File Systems[1].
