I started with a few hundred gig on my FS (on top of LVM which in turn is on top a bunch of MD devices). Slowly increasing the size with pvmove/{vg,lv}extend etc. Yesterday, I added more disks yet again and now have about 8Tb on one FS... ~1Tb free. But still get the 'No space left on device'. I've been looking through the 'Net and it must be because I'm out of inodes (and that the data is on the first 1Tb etc)... I'm running on AMD 64bit (native kernel, but Debian Lenny 32bit userland - 2.6.2[4-6] kernel). Now, if I use (I'll try to upgrade to a newer kernel so I can reverse) the inode64, what impact will this have? I guess I still have to move my firstly created 1Tb of-disk and then back again? The worst thing is that every time I grow the FS, I have to reboot into a 32bit kernel: xfs_growfs: XFS_IOC_FSGROWFSDATA xfsctl failed: Invalid argument and then back to the 64bit kernel... How will this (system/FS) react if I go 64bit inodes?! And how safe is this!? I just don't have the possibility to do a full backup of all this data, not even temporarily... I _might_ be able to do this in a few weeks (work is ordering a bunch of LaCie 8Tb USB/eSATA storage boxes which I might be able to load for a few days 'to do some stress testing on' :) References: http://xfs.org/index.php/XFS_FAQ#Q:_Why_do_I_receive_No_space_left_on_device_after_xfs_growfs.3F http://xfs.org/index.php/XFS_FAQ#Q:_Can_I_just_try_the_inode64_option_to_see_if_it_helps_me.3F http://www.doc.ic.ac.uk/~dcw/xfs_16tb/ _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
