Hi ! My system is RH7.2 with Adaptec/DPT/I2O drivers (http://people.redhat.com/tcallawa/dpt/). There is a 2 disk RAID 1 array which had no disk fail. Several partition on it: Filesystem Size Used Avail Use% Mounted on /dev/sda1 1.9G 435M 1.4G 24% / /dev/sda2 13G 3.2G 9.1G 26% /home none 504M 0 503M 0% /dev/shm At this time, all seems to be ok. But there was in /etc/log/message Aug 13 10:55:40 web kernel: EXT3-fs error (device sd(8,1)): ext3_free_blocks: Freeing blocks not in datazone - block = 439612, count = 1 Aug 13 10:55:41 web syslogd: /var/log/maillog: No space left on device Aug 13 10:55:40 web kernel: EXT3-fs error (device sd(8,1)): ext3_free_blocks: Freeing blocks not in datazone - block = 439611, count = 1 Aug 13 10:55:41 web kernel: EXT3-fs error (device sd(8,1)): ext3_free_blocks: Freeing blocks not in datazone - block = 401302, count = 1 Aug 13 10:55:41 web kernel: EXT3-fs error (device sd(8,1)): ext3_new_block: block(1852807394) >= blocks count(1651339086) - block_group = 0, es == f78b6400 Aug 13 10:55:41 web kernel: EXT3-fs error (device sd(8,1)): ext3_new_block: block(1852807395) >= blocks count(1651339086) - block_group = 0, es == f78b6400 Aug 13 10:55:41 web kernel: EXT3-fs error (device sd(8,1)): ext3_new_block: block(1852807396) >= blocks count(1651339086) - block_group = 0, es == f78b6400 Only the first partition is damaged (/dev/sda1) but that's the / in the fs. Filesystem Size Used Avail Use% Mounted on /dev/sda1 15T 15T 0 100% / /dev/sda2 13G 3.2G 9.1G 26% /home none 504M 0 503M 0% /dev/shm or something like that... I have already tried to install the RH7.3 (with no need dpt drivers), but it was the same problem. That's curieus because, I have ran redhat 7.2 for a long time without problem like that and I have updated frequently (maybe the raison of that error). Any idea ? Séb.
