I hope I'm not asking a too pettty of a question for this list! We are planning to add a 3 rd EXP300 array to out current server w/ 2 EXP300's in place already! We WILL surpass the 1 TB size, if possible? A little history: Linux ptb3 2.2.19 #2 SMP Tue Jul 24 11:53:29 CDT 2001 i686 unknown I have two IBM EXP300 RAID arrays connected to a Netfinity 4500R running Redhat Linux 6.2. LVM compiled into kernel AFAIK...w/ patch? We are using: lvm_0.9.1_beta7 reiserfsprogs-3.x.0j Here is the current filesystem and size: /dev/exp300_2/exp300_lv2 924160464 891307744 32852720 97% /files1 Just wondering about this faq: Q: Why are my logical volumes limited to 256 GB in size? A: This is NO absolute limit but it depends on the physical extent size you configured at volume group creation time. Please use option -s of the vgcreate command to give a larger physical extent size. For example with a physical extent size of 524288 KB (512 MB) you are able to map a logical volume of 32 Terabyte. Remember that current Linux kernels are limited to 1 Terabyte. ***Especially about the part in bold! Please let me know if you need more details, I will supply asap!

A little history:

Linux ptb3 2.2.19 #2 SMP Tue Jul 24 11:53:29 CDT 2001 i686 unknown

I have two IBM EXP300 RAID arrays connected to a Netfinity 4500R running Redhat Linux 6.2.
LVM compiled into kernel AFAIK...w/ patch?

We are using:
lvm_0.9.1_beta7
reiserfsprogs-3.x.0j

Here is the current filesystem and size:

/dev/exp300_2/exp300_lv2 924160464 891307744  32852720      97% /files1

Just wondering about this faq:

                           Q:
                               Why are my logical volumes limited to 256 GB in size?
                           A:
                               This is NO absolute limit but it depends on the physical extent size you configured at volume group
                               creation time.

                               Please use option -s of the vgcreate command to give a larger physical extent size. For example with a
                               physical extent size of 524288 KB (512 MB) you are able to map a logical volume of 32 Terabyte.
                               Remember that current Linux kernels are limited to 1 Terabyte.

***Especially about the part in bold!

Please let me know if you need more details,  I will supply asap!

TIA!
