a colleague recently tried to grow a 16 TB filesystem (x86, 32bit) on top of lvm2 to 17TB. (I am not even sure if that's supposed work with linux-2.6, 32bit) used kernel seems to be debian sarge's 2
If you have CONFIG_LBD enabled (do you?), it should in theory, barring bugs :) hmm old.... trace below looks like not... in the growfs thread here This is checking: if (unlikely( sbp->sb_dblocks == 0
Not supported - any metadata access past 16TB will wrap the 32 bit page cache index for the metadata address space and you'll corrupt the filesystem. No, growfs failed trying to extend the data parti
That looks like an overflow to me ;) Free space gone kaboom too... Which is just less than 16TB: 0x1ffeffaf0000 Which is just more than 16TB: 0x2008ccb00000 Probably corrupted metadata in the first c

isn't the AG size 'agblocks * blocksize' == ~324 GB here ? got further input on a secondray superblock form the colleague: looks more reasonable, I'd say. Is there a way to manually recover sb0 from

Good idea, Eric. I've created a pv. I noticed this was taken from xfs_mount_validate_sb() for the dblocks test. I guess it would be nice to abstract this test in a macro for use in multiple places. C

... for your info - with recent xfsprogs (2.8.11) repair (on a 32bit system) succeeded. No xfs_db magic needed. thanks again for your help, cheers. - Christian
Yes, you are right - I was thinking 512 byte blocks which then gave the right size that you grew to. Otherwise 570*324GB gives 200TB, which is somewhat larger than you apparently tried to grow to...
