fsck ran on a filesystem hosting an oracle DB ?
One of our tasks in the office is to do database backups. We were taught (us all operators working here) that it is done via a bunch of specialized scripts. Those scripts are at least 10 years old (system is an AIX 4.1).
One of those script does an fsck against the databases. Everytimes we run it we see a message saying something like running an fsck against a filesystem does not produce reliable results. The databases are in Oracle 7.(something) and are located in a file system on each servers we do it.
All of what the script does is "fsck -n /db_componant_on_a_filesystem".
Is this a good idea to do this ? We are questioning how some of the scripts/tasks are done because we believe (or think) they are either wrong or should be done in a different manner.

systemd-fsck
SYSTEMD-FSCK@.SERVICE(8) systemd-fsck@.service SYSTEMD-FSCK@.SERVICE(8)
NAME
systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck - File system checker logic
SYNOPSIS
systemd-fsck@.service
systemd-fsck-root.service
/lib/systemd/systemd-fsck
DESCRIPTION
systemd-fsck@.service and systemd-fsck-root.service are services responsible for file system checks. They are instantiated for each device
that is configured for file system checking. systemd-fsck-root.service is responsible for file system checks on the root file system, but
only if the root filesystem was not checked in the initramfs. systemd-fsck@.service is used for all other file systems and for the root
file system in the initramfs.
These services are started at boot if passno in /etc/fstab for the file system is set to a value greater than zero. The file system check
for root is performed before the other file systems. Other file systems may be checked in parallel, except when they are on the same
rotating disk.
systemd-fsck does not know any details about specific filesystems, and simply executes file system checkers specific to each filesystem
type (/sbin/fsck.*). This helper will decide if the filesystem should actually be checked based on the time since last check, number of
mounts, unclean unmount, etc.
If a file system check fails for a service without nofail, emergency mode is activated, by isolating to emergency.target.
KERNEL COMMAND LINE
systemd-fsck understands these kernel command line parameters:
fsck.mode=
One of "auto", "force", "skip". Controls the mode of operation. The default is "auto", and ensures that file system checks are done
when the file system checker deems them necessary. "force" unconditionally results in full file system checks. "skip" skips any file
system checks.
fsck.repair=
One of "preen", "yes", "no". Controls the mode of operation. The default is "preen", and will automatically repair problems that can be
safely fixed. "yes" will answer yes to all questions by fsck and "no" will answer no to all questions.
