Hi all, my attempt to format a new OST failed (mkfs.lustre: Unable to mount /dev/sdd: Invalid argument), obviously because sdd has "device size = 15253504MB", and the log tells me 'LDISKFS-fs does not support filesystems greater than 8TB and can cause data corruption.'
However, this is a Lustre 1.8.4 installation, I have compiled the kernel and modules myself and I have checked the 'modules/lustre/ldiskfs - config.log' to start with the following: It was created by Lustre ldiskfs configure 3.1.3, which was generated by GNU Autoconf 2.61. Invocation command line was $ ./configure --prefix=/usr --with-linux=/usr/src/linux-2.6.27.39-0.3 --disable-quilt --disable-dependency-tracking --disable-doc --disable-utils --disable-liblustre --enable-snmp --enable-ldiskfs --disable-zerocopy --disable-tests --enable-quota CC=gcc-4.3 --enable-ext4 --with-lustre-hack --with-sockets --cache-file=/dev/null --srcdir=. All subsequent references to ext4 in this config.log seem to indicate that my ldiskfs should be based on ext4 and thus be able to handle a large device. Is there a way to check ask the module itself about its capabilities? Or is there perhaps a magic switch for mkfs.lustre?
