11.23 file system over 1TB

[brenda perez]

Hello,

I have been reading the documentation and forum and it seems that with HP-UX 11.23 I should be able to create a 2TB file system. My volume group is 4TB. Originally I used the command line to do my vgcreate, etc but it would only create a file system of 4GB. I then used SAM and it created a max file system of 1TB but wouldn't create it any larger. Here is the output from my fstyp:
rldsasp1#fstyp -v /dev/vgase/asenapine
vxfs
version: 5
f_bsize: 8192
f_frsize: 1024
f_blocks: 1073610752
f_bfree: 1073331141
f_bavail: 1006247945
f_files: 268332816
f_ffree: 268332784
f_favail: 268332784
f_fsid: 1074200577
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 16
f_fsindex: 10
f_size: 1073610752

Here's my output from my vgdisplay:
--- Volume groups ---
VG Name /dev/vgase
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 1
Open LV 1
Max PV 16
Cur PV 2
Act PV 2
Max PE per PV 65376
VGDA 4
PE Size (Mbytes) 128
Total PE 32682
Alloc PE 8191
Free PE 24491
Total PVG 0
Total Spare PVs 0
Total Spare PVs in use 0

When I tried to do an extendfs it said it was at maximum device capacity.
I do not have Online JFS installed because it wasn't purchased with this server.

Any ideas?

Shalom,

re-create the volume group.

Use the option -p 5 (some number) To allow PE's to be spread over fewer disks. In the default configuration they are reserved for 255 disks.

Or -s (size) Use bigger PE size.

Thanks for the reply. My PE size is set to 128 though, so the volume group should be able to account for 4TB. When I create the logical volume of 4TB it doesn't give an error, it's when I try to make a file system that it gives me the 1TB limitation.

Thanks - that is what I originally was looked at that said I should be able to create a maximum supported file system size of 32TB but it's only letting me create a 1TB.

vgcreate -s 32 -p 128 -e 65376 /dev/vgase /dev/dsk/cXtXdX /dev/dsk/cXtXdX
lvcreate -L 2097152 -n asenapine /dev/vgase


Then newfs it....

thanks for all the replies. FYI - I did get it to work - originally I had created the logical volume as 4TB because I had wanted a 4TB file system. The response center confirmed that without Online JFS I could only create a 2TB file system. Also, they said using SAM to do the creation has been known to cause issues so the commandline is best. When I created my volume group of 4TB and logical volumes of 2TB each I was able to use the newfs command. Previously it was giving a license error when i used newfs.
