Recently, I noticed messages like the following on two laptops with very different hardware, but both running Fedora 21, updated daily:
/var/log/messages-20150216:Feb 12 18:47:36 lenov kernel: [181055.262390] EXT4-fs error (device sda3): __ext4_new_inode:1010: comm NetworkManager: failed to insert inode 262402: doubly allocated? /var/log/messages-20150224:Feb 23 21:54:30 lenov kernel: [510707.869736] EXT4-fs error (device sda3): ext4_mb_generate_buddy:757: group 34, block bitmap and bg descriptor inconsistent: 15366 vs 15373 free clusters
On both machines, the affected partition is the root partition. The problem is bad enough that it needs an fsck from a rescue disk. smartctl -a /dev/sda doesn't signal any error, but the disks failing on different machines simultaneously is unlikely anyway, especially that this happened sometime in January, too, also with the same laptops, also roughly at the same time.
The January error (but not the present one) may be the one reported here: https://bugzilla.redhat.com/show_bug.cgi?id=1154467
