File System Error: BAD SUPERBLOCK AT BLOCK 16: NUMBER OF DIRECTORIES OUT OF RANGE
Hi All,
we are having a file system error in one of our servers. The server failed to boot in usual user mode. Instead boot with single user mode and requesting to run a FSCK manually to repair the corrupted. see the below output.
When we try to run the fsck it prompts to look for the superblocks using either MKFS or NEWFS, According to the oracle documentation, we need to select it correctly depending on the system. But we do not know from which command the file system is created. so with the warning given, we want get an advise on the best possible way to proceed for the file system repair.

The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and really contains a valid an ext2 filesystem (and... (1 Reply)

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.
