Error while running fsck

Sawant — Tue, 17 May 2011 10:15:48 GMT

Dear Experts,

We are facing file system check failure error while executing below command on /dev/vol11/lvol3

Please find the error logs below:

fileset 999 primary-ilist inode 99016 dup block
extent start 11630848 offset 39 continue? (ynq)y
fileset 999 primary-ilist inode 99016 dup/bad blocks found clear? (ynq)y
vxfs fsck: malloc failed, add more swap space
file system check failure, aborting ...

Please suggest how to mount the filesytem in this situation.

Hi,
I've found a similar thread matching your problem:

fsck -F vxfs -o full ....
malloc failed! add more swap space

swapinfo -t .... is ok

increased maxdsiz from 64mb to 128mb solved the problem

bye

You might be able to mount the filesystem in read-only mode without checking it first.

mount -o ro /dev/vol11/lvol3

The messages you posted indicate the filesystem contains errors: before mounting the filesystem in normal read/write mode, it is recommended (or sometimes it might be even required) to successfully complete a filesystem check first.

The error message already told you how to allow fsck to proceed: "add more swap space".

First, you probably should run "swapon -a" before re-running the filesystem check, to ensure all the configured swap areas are activated. If that is not enough, do you have unallocated disk space you could use for creating a new swap LV? Or do you have free disk space on some other filesystem you could use for temporary filesystem swap?

Run "man 1m swapon" for instructions on activating new LVs as swap, or on creating a filesystem swap area.

Thanks... Although I am able to mount the file system but it is in read only mode.

If I want to use the filesystem, I need to change it to read write mode which can only be done using "mount -F vxfs -o rw /dev/vol11/lvol3 /volume". For this we need to unmount it first. Mounting command gives corrupt filesystem for which we need to give fsck command which is again giving the same error.

Kindly suggest how to make the file system in readwrite mode.

Did you try to increase the value of the kernel parameter maxdsiz / maxdsiz_64bit as suggested?

What OS release do you have?

HP-UX B.11.11 U is the version.

Details for swapinfo as below. It got 4 GB of memory

so try to adjust the kernel parameter as suggested. Although it's not a dynamic parameter, so you would need to reboot....

Kindly suggest the steps/syntax for the same.

The easiest way for you to do this if you don't like command line is via SAM. It's a GUI/TUI . You need to go to Kernel configuration --> Configurable parameters . Modify those 2 parameters accordingly and then in the Actions tab --> Process new Kernel. It's going to reboot the system afterwards.
