I currently have PV's around 5.46TiB here but have had them up to 10TiB on other machines. Don't know what the max size is though.

I'm sorry I have to ask this question to this mailing list, but I have not been able to find sufficient and conclusive informaiton on the web. The mailing-list archive at redhat seems not to be searchable. What is the maximum size of a PV in LVM2? I run linux 2.6.24 kernel (Ubuntu server 8.04 LTS, 32bit i386) with lvm2 2.02.26 and mdadm 2.6.3. The kernel has CONFIG_LBD=y in its configuration. I currently use a 2TB (just under 2TB, 1.98TB actually) raid5 array /dev/mdN as the one and only PV in a VG. I would like to grow the array by addition of another disk to 3TB and then expand the PV. As far as I understand mdadm, on a kernel with LBD support it should be able to create a blockdevice >2TB, but I am not sure that LVM2 will accept it as a PV. The LVM2-Howto on TLDP (<a class="moz-txt-link-freetext" href="http://tldp.org/HOWTO/LVM-HOWTO/lvm2faq.html">http://tldp.org/HOWTO/LVM-HOWTO/lvm2faq.html</a>) confirms that LVs can be >2TB (16TB on 32bit OS, 8EB on 64bit OS), but says nothing at all about PVs. Could somebody add that information? thanx for support kind regards, Sulla -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.1 (MingW32) Comment: Using GnuPG with Mozilla - <a class="moz-txt-link-freetext" href="http://enigmail.mozdev.org/">http://enigmail.mozdev.org/</a> iD8DBQFLPxplR6b2EdogPFsRApOQAKCq5lWWCZEU3lOqDN0yNwtjSWTx/wCfb7Bu m2SeTwsAeRU3008a1RvWBC8= =IBoj -----END PGP SIGNATURE----- _______________________________________________ linux-lvm mailing list <a class="moz-txt-link-abbreviated" href="mailto:linux-lvm@redhat.com">linux-lvm@redhat.com</a> <a class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/linux-lvm">https://www.redhat.com/mailman/listinfo/linux-lvm</a> read the LVM HOW-TO at <a class="moz-txt-link-freetext" href="http://tldp.org/HOWTO/LVM-HOWTO/">http://tldp.org/HOWTO/LVM-HOWTO/</a> </pre> </blockquote> </body> </html>
