Re: filesystem more than 2 TB

you can find answer in this thread :
http://forums11.itrc.hp.com/service/forums/questionanswer.do?admit=109447626+1236935094943+28353475&threadId=1124935

it is said : "2TB Filesystems are only allowed with VxVM as your Volume Manager *and* VxFS (OJFS) versions greater than 3.5m (4.1 is preferred) and for VxFS Layout >4.0."

It's a rather old thread, and I don't know if VxVM is still required as long as you managed to create a 3TB LV. But do you at least have Online JFS installed ?

Regards,

Fred

Re: filesystem more than 2 TB

Hi,

Please refer to
docs.hp.com/en/6054/LVM_Limits_White_Paper_V4.pdf

You could have FS of only 2TB in LVM 1.0
From LVM 2.0 you could have FS of 16TB.

Re: filesystem more than 2 TB

Also
JFS layout version of 4 had a 2Gb limitation
JFS 4.1 supports layout_versions up to version 6.
To increase the maximum filesystem limit, upgrade to layout_version 5

NOTE: - OnlineJFS is required for larger then 2TB filesystems.


11.23 mkfs_vxfs manpage:


VxFS Version 5 Disk Layout File System Sizes
The Version 5 disk layout supports file systems up to 32 terabytes.
The maximum size of the file system you can create depends on the
block size. (The actual maximum file system size is slightly less
than the maximum values in bytes, described below.)

The following table defines the file system sizes and their associated
values:

------------------------------------------
| Maximum File System Size
------------------------------------------------------
Block Size | In sectors | In bytes
------------------------------------------------------
1024 bytes | 4,294,967,039 | approximately 4 TB
2048 bytes | 8,589,934,078 | approximately 8 TB
4096 bytes | 17,179,868,156 | approximately 16 TB
8192 bytes | 34,359,736,312 | approximately 32 TB
------------------------------------------------------

Re: filesystem more than 2 TB

Yes, for file systems over 2TB, you will need the "OnlineJFS" license...this is a separate product/license.

e.g.

# swlist -l bundle -l product|grep -i JFS
# B3929EA B.11.31 HP OnLineJFS (Server)
