On my laptop (this is a *laptop*, mind you): % df -i /home Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/VolGroup00-home 655360 532361 122999 82% /home What happens if I do a 'mv /home /home1'? Looks like more than a "relatively small" number. A cold-cache 'find' takes a few minutes to wade through it all, so any solutions you come up with should beware of locking issues... --==_Exmh_1187278162_618P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFGxG1ScC3lWbTT17ARApU7AJ91L2jl43Lg13kefLbTlvYB+0fBTwCfVq4x ipCVErpDU7d6HmhUrh0GDwQ= =ci+c -----END PGP SIGNATURE----- --==_Exmh_1187278162_618P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
