I have a Solaris 7 box. We got a strange error in the syslog, which read as follows:
I consulted with a fellow sysadmin, and he suggested running "fsck -N" on the filesystem in question without unmounting it. So I did, and got a bunch of errors that read as follows:
these are just examples. Should I worry about these? I'm thinking that mounted file system with active processes would always be "dirty". But I'm not sure that I'm even supposed to run fsck on a mounted file system, even with -N option. Is -N option save or am I doing some kind of a damage?

I am having a problem with fsck. I am new to UNIX but was placed in a position where I must learn it. Anyway, one of the instructions that I have been given is to use 'fsck -f -y' when I am having trouble with the filesystem. The problem is that I am getting an error message that says the -f...

Hi,

fsck.ocfs2
fsck.ocfs2(8) OCFS2 Manual Pages fsck.ocfs2(8)NAME
fsck.ocfs2 - Check an OCFS2 file system.
SYNOPSIS
fsck.ocfs2 [ -pafFGnuvVy ] [ -b superblock block ] [ -B block size ] device
DESCRIPTION
fsck.ocfs2 is used to check an OCFS2 file system.
device is the file where the file system is stored (e.g. /dev/sda1). It will almost always be a device file but a regular file will work
as well.
OPTIONS -a This option does the same thing as the -p option. It is provided for backwards compatibility only: it is suggested that people use
the -p option whenever possible.
-b superblock block
Normally, fsck.ocfs2 will read the superblock from the first block of the device. This option specifies an alternate block that the
superblock should be read from. (Use -r instead of this option.)
-B blocksize
The block size, specified in bytes, can range from 512 to 4096. A value of 0, the default, is used to indicate that the blocksize
should be automatically detected.
-D Optimize directories in filesystem. This option causes fsck.ocfs2 to coalesce the directory entries in order to improve the filesys-
tem performance.
-f Force checking even if the file system is clean.
-F By default fsck.ocfs2 will check with the cluster services to ensure that the volume is not in-use (mounted) on any node in the
cluster before proceeding. -F skips this check and should only be used when it can be guaranteed that the volume is not mounted on
any node in the cluster. WARNING: If the cluster check is disabled and the volume is mounted on one or more nodes, file system cor-
ruption is very likely. If unsure, do not use this option.
-G Usually fsck.ocfs2 will silently assume inodes whose generation number does not match the generation number of the super block are
unused inodes. This option causes fsck.ocfs2 to ask the user if these inodes should in fact be marked unused.
-n Give the 'no' answer to all questions that fsck will ask. This guarantees that the file system will not be modified and the device
will be opened read-only. The output of fsck.ocfs2 with this option can be redirected to produce a record of a file system's
faults.
-p Automatically repair ("preen") the file system. This option will cause fsck.ocfs2 to automatically fix any problem that can be
safely corrected without human intervention. If there are problems that require intervention, the descriptions will be printed and
fsck.ocfs2 will exit with the value 4 logically or'd into the exit code. (See the EXIT CODE section.) This option is normally used
by the system's boot scripts.
-r backup-number
mkfs.ocfs2 makes upto 6 backup copies of the superblock at offsets 1G, 4G, 16G, 64G, 256G and 1T depending on the size of the vol-
ume. Use this option to specify the backup, 1 thru 6, to use to recover the superblock.
-y Give the 'yes' answer to all questions that fsck will ask. This will repair all faults that fsck.ocfs2 finds but will not give the
operator a chance to intervene if fsck.ocfs2 decides that it wants to drastically repair the file system.
-v This option causes fsck.ocfs2 to produce a very large amount of debugging output.
-V Print version information and exit.
EXIT CODE
The exit code returned by fsck.ocfs2 is the sum of the following conditions:
0 - No errors
1 - File system errors corrected
2 - File system errors corrected, system should
be rebooted
4 - File system errors left uncorrected
8 - Operational error
16 - Usage or syntax error
32 - fsck.ocfs2 canceled by user request
128 - Shared library error
