I am trying to root disk mirroring on SunFire V210 Server. There are two disks on this server c1t0d0 and c1t1d0 . I completed all the steps and I updated the vfstab file too. After I have updated the vfstab file I run df -h command but could not see the changes i made in vfstab. Suddenly the server got rebooted automatically and I could not boot the server. So I put the solaris 10 cd and did boot cdrom -s and mount /dev/dsk/c1t0d0s0 /a . Then I tried to do the fsck /dev/dsk/c1t0d0s0 but could not do that. c1t0d0s0 has the mount point /. Could any one give me a hint or suggestion on why I cant run fsck command.thanks in advance.

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...

I have a Solaris 7 box. We got a strange error in the syslog, which read as follows:
Nov 15 11:50:16 server-01 unix: NOTICE: free inode /mount1/8025691 had size 0x20d
I consulted with a fellow sysadmin, and he suggested running "fsck -N" on the filesystem in question without unmounting it. So I... (1 Reply)

Hello.
I have created a FS /u00/ and created a non-root login under this FS. Also, disabled direct root login. Now is it possible or worth moving this login over to the root partition or allowing mount/umount + fsck from a standard account. As I am not able to run fsck for this FS.

Hi,
I need to fsck the root file system on my Solaris 9 server. It is a UFS file system but it is under Veritas control. I want to know which fsck I need to use to check the file system. The default Solaris fsck (/usr/sbin/fsck) or the Veritas (/lib/fs/vxfs/sparcv9/fsck) fsck? I take it I... (3 Replies)
I have a CentOS release 5.2 (Final)host running kernel 2.6.18-92.el5 with at raid 10 that had two mirrored drives fail. The drives were re-inserted and now the raid shows healthy (for now). I tried to mount but got an Input/output error. I then attempted a fsck:

If i run fsck on one filesystem and fsck need to repair some things then this partition must be unmounted
correct ?
So running fsck on root file system isn't possible within same OS ? correct ?
What is the best way to do that, live cd ?

vfstab - table of file system defaults
DESCRIPTION
The file /etc/vfstab describes defaults for each file system. The information is stored in a table with the following column headings:
device device mount FS fsck mount mount
to mount to fsck point type pass at boot options
The fields in the table are space-separated and show the resource name (device to mount), the raw device to fsck (device to fsck), the
default mount directory (mount point), the name of the file system type (FS type), the number used by fsck to decide whether to check the
file system automatically (fsck pass), whether the file system should be mounted automatically by mountall (mount at boot), and the file
system mount options (mount options). (See respective mount file system man page below in SEE ALSO for mount options.) A '-' is used to
indicate no entry in a field. This may be used when a field does not apply to the resource being mounted.
The getvfsent(3C) family of routines is used to read and write to /etc/vfstab.
/etc/vfstab can be used to specify swap areas. An entry so specified, (which can be a file or a device), will automatically be added as a
swap area by the /sbin/swapadd script when the system boots. To specify a swap area, the device-to-mount field contains the name of the
swap file or device, the FS-type is "swap", mount-at-boot is "no" and all other fields have no entry.
EXAMPLES
The following are vfstab entries for various file system types supported in the Solaris operating environment.
Example 1: NFS and UFS Mounts
The following entry invokes NFS to automatically mount the directory /usr/local of the server example1 on the client's /usr/local directory
with read-only permission:
example1:/usr/local - /usr/local nfs - yes ro
The following example assumes a small departmental mail setup, in which clients mount /var/mail from a server mailsvr. The following entry
would be listed in each client's vfstab:
mailsvr:/var/mail - /var/mail nfs - yes intr,bg
The following is an example for a UFS file system in which logging is enabled:
/dev/dsk/c2t10d0s0 /dev/rdsk/c2t10d0s0 /export/local ufs 3 yes logging
See mount_nfs(1M) for a description of NFS mount options and mount_ufs(1M) for a description of UFS options.
Example 2: pcfs Mounts
The following example mounts a pcfs file system on a fixed hard disk on an x86 machine:
/dev/dsk/c1t2d0p0:c - /win98 pcfs - yes -
The example below mounts a Jaz drive on a SPARC machine. Normally, the volume management daemon (see vold(1M)) handles mounting of remov-
able media, obviating a vfstab entry. If you choose to specify a device that supports removable media in vfstab, be sure to set the mount-
at-boot field to no, as below. Such an entry presumes you are not running vold.
/dev/dsk/c1t2d0s2:c - /jaz pcfs - no -
For removable media on a SPARC machine, the convention for the slice portion of the disk identifier is to specify s2, which stands for the
entire medium.
For pcfs file systems on x86 machines, note that the disk identifier uses a p (p0) and a logical drive (c, in the /win98 example above) for
a pcfs logical drive. See mount_pcfs(1M) for syntax for pcfs logical drives and for pcfs-specific mount options.
Example 3: CacheFS Mount
Below is an example for a CacheFS file system. Because of the length of this entry and the fact that vfstab entries cannot be continued to
a second line, the vfstab fields are presented here in a vertical format. In re-creating such an entry in your own vfstab, you would enter
values as you would for any vfstab entry, on a single line.
device to mount: svr1:/export/abc
device to fsck: /usr/abc
mount point: /opt/cache
FS type: cachefs
fsck pass: 7
mount at boot: yes
mount options:
local-access,bg,nosuid,demandconst,backfstype=nfs,cachedir=/opt/cache
See mount_cachefs(1M) for CacheFS-specific mount options.
Example 4: Loopback File System Mount
The following is an example of mounting a loopback (lofs) file system:
/export/test - /opt/test lofs - yes -
See lofs(7FS) for an overview of the loopback file system.
