Creating a new FS hangs

[Arunvijai_4]

Hi Gurus,

I am trying to create a new FS in HP-UX 11.11 using mkfs.

# mkfs -F vxfs /dev/rdsk/c9t0d0
version 4 layout
46080 sectors, 46080 blocks of size 1024, log size 1024 blocks
unlimited inodes, largefiles not supported
46080 data blocks, 44976 free data blocks
2 allocation units of 32768 blocks, 32768 data blocks
last allocation unit has 13312 data blocks


and it hangs here... /dev/rdsk/c9t0d0 is a symmetrix disk.

# /usr/symcli/bin/syminq

Device Product Device

Any ideas will helpful.

Have you done a pvcreate first

pvcreate -f /dev/rdsk/c9t0d9

[RAC_1]

I hope you did pvcreate before that.
Also what does diskinfo say??
Is disk good?? Run dd on it.
dd if=/dev/rdsk/cxtxdx of=/dev/null bs=1024k

Also run mkfs with -V option and post.

Hi again,

I tried pvcreate, diskinfo, mkfs -v /dev/rdsk/c9t0d0, and no output. I couldn't even kill the processes.

ioscan -fnCdisk. Is it claimed in ioscan??
If yes, insf -ev -Cdisk.

Looks like old mkfs command is hung, waiting on i/o. You can not kill it then.

Create physical volume:
pvcreate /dev/rdsk/c9t0d0

Create dev file:
mkdir /dev/

Create volume group:
vgcreate -s 8 -e /dev/ /dev/dsk/c9t0d0
lvcreate -L /dev/

Create file system:
newfs -F vxfs -o largefiles /dev//rlvol

Create mount point:
mkdir /

Mount:
mount /dev//lvol //

Hi Arun

Following steps may help:

1. #pvcreate /dev/rdsk/c9t0d0
2. #insf -e
2. mkfs -F vxfs /dev/rdsk/c9t0d0

If system hangs during mkfs, there is possibility that disk is defective. Run "dd"command to verify the disk or if online diagnostics are installed, run disk diagnostic for thorough verification of media

Mahesh

Arun,

This looks like a peculiar problem for me. I would advice you to try this, but to be frank enough, Im not sure, if it would work:

Reboot the system and bring it up in single user mode. (This would get rid of any previous mkfs / ioscan hung commands )

If required, mount the filesystems in vg00 manually.

pvcreate -F /dev/rdsk/c9t0d0 (This is a destructive command. Be sure of the disk path)

Look for any errors.

Your disk size is 47 GB.

Create a new vg. The commands are already in the above responses, but still...

mkdir /dev/vg09
mknod /dev/vg09/group c 64 0x090000
vgcreate /dev/vg09 /dev/dsk/c9t0d0
vgchange -a y vg09

If this was succesful, then we'll create a smaller lv...

lvcreate -L 1024 /dev/vg09

Lets try an HFS file system...

mkfs -F hfs /dev/vg09/lvol1

Keep your fingers crossed, to see if this completes succesfully. If it did, mount it to any folder, and look for errors while mounting. If it did'nt, call up the EMC guy and ask him to work with you to resolve this issue.

If it did complete, unmount it and create a vxfs file system...

mkfs -F vxfs /dev/vg09/lvol1

If succesful, you have reasons to be happy. If not, ??? Well, I think It would.

Mount this on to some folder and check.

Extend the lv size to say 40 GB

lvextend -L 40960 /dev/vg09/lvol1
fsadm -b 40960M
If you came thus far, you could still go near the 47 GB mark and see where it stops working. I would contact EMC to find out why I cant use the whole 47 GB in one shot...

Cheers!

Hi,

It is not always required to create a PV,VG,LV on a disk to access it, allthough it is recommended. If intentionally you need to create a file system on disk without LVM, it should not take much time and should be completed. This is some issue with your EMC array and I remember a recent thread which invloved some EMC problem which was rectified later and sorted out similar problem.

Also ensure latest patches.

Anoop - We are not sure wheather onlineJFS is installed to extend file system online.

Hi,

I noticed /dev/dsk/disk_query into ioscan output. I should think that it is not so normal.
I usually saw it sometimes when creating a VG by SAM.
Did you extend this disk into this VG by SAM?

Anyway I would suggest:

- remove those special files:
rmsf /dev/dsk/disk_query
rmsf /dev/rdsk/disk_query

- vgreduce the VG about that disk:
vgreduce /dev/vgXX /dev/dsk/c9t0d0

- pvcreate again:
pvcreate -f /dev/rdsk/c9t0d0

- vgextend again:
vgextend /dev/vgXX /dev/dsk/c9t0d0

- and I usually prefer to use newfs even if it recalls mkfs:

newfs -F vxfs /dev/rdsk/c9t0d0

Let us know if it helps.

Best regards,
Fabio

Devendar,

"I am trying to create a new FS in HP-UX 11.11 using mkfs. "

Online JFS is a part of HPUX 11.11 by default. Hence I'm sure that we could extend it online, unless there is a media issue.

Anoop

Hi,

Online JFS is not part of standard OS bundle in any release? It is a seperate licensed product.

At the beginning of the post, you are using newfs for the entire disk so it does not need to have pvcreate, vgcreate and lvcreate. Is this what you want to do? However, the output from ioscan and hangs from the other disk commands is likely the problem. Your system cannot communicate with the disk at the driver level. You'll have to review the EMC docs on how to connect the disk (and make it active) to your system. Until diskinfo works, there is no point trying anything else.
