Hope it's okay to send "user problems" here. I've made a 15TB logical volume on a 21TB RAID6 iSCSI array. When I try to make an ext4 filesystem I see the following error: mke4fs -E stride=32 stripe-width=384 -i 65536 -j -v \ /dev/mapper/vg2md3000isata-homes2 mke4fs 1.41.9 (22-Aug-2009) mke4fs: invalid blocks count - /dev/mapper/vg2md3000isata-homes2 Some more details: --- Physical volume --- PV Name /dev/mpath/mpath4 VG Name vg2md3000isata PV Size 21.83 TB / not usable 32.00 MB Allocatable yes PE Size (KByte) 32768 Total PE 715205 Free PE 223685 Allocated PE 491520 PV UUID psv5BF-Tkvv-p7uq-ED0k-DCPd-3es1-uNnNSg --- Logical volume --- LV Name /dev/vg2md3000isata/homes2 VG Name vg2md3000isata LV UUID qieiLw-F0he-DlDD-bZeA-v2Ok-DmE5-oS3uy2 LV Write Access read/write LV Status available # open 0 LV Size 15.00 TB Current LE 491520 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:11 --- Volume group --- VG Name vg2md3000isata System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 2 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 0 Max PV 0 Cur PV 1 Act PV 1 VG Size 21.83 TB PE Size 32.00 MB Total PE 715205 Alloc PE / Size 491520 / 15.00 TB Free PE / Size 223685 / 6.83 TB VG UUID vLwJLm-z1gj-RZrM-GjXX-hmLo-cf6B-8EGMyR When i searched briefly yesterday, some documentation stated that the filesystem limit was now 16TB, and some that the limit was much higher. The system is running Centos 5.5, e4fsprogs-1.41.9-3.el5.
