| + | = Disable Auto FileSystem Check on SLES | ||
| + | On SLES 10, the sytem performs an auto check on the file systems by default. This can be very annoying when performing an emergency reboot on a production system. This behavior is adjusted for SLES 11 but as far as I am concerned I'd still check the setting. | ||
| + | |||
| + | = Devices | ||
| + | The setting is set on a device, which can be checked using the simple command fdisk: | ||
| + | |||
| + | <code> | ||
| + | fdisk -l | ||
| + | |||
| + | Disk /dev/sda: 12.9 GB, 12884901888 bytes | ||
| + | 255 heads, 63 sectors/track, 1566 cylinders | ||
| + | Units = cylinders of 16065 * 512 = 8225280 bytes | ||
| + | Disk identifier: 0x000988d6 | ||
| + | |||
| + | Device Boot Start End Blocks Id System | ||
| + | /dev/sda1 1 191 1534176 82 Linux swap / Solaris | ||
| + | /dev/sda2 * 192 1566 11044687+ 83 Linux | ||
| + | </code> | ||
| + | |||
| + | = Settings | ||
| + | You can check the file system properties for each device using the tun2fs command: | ||
| + | <code> | ||
| + | # tune2fs -l /dev/sda2 | ||
| + | ....cut... | ||
| + | Maximum mount count: 500 | ||
| + | Last checked: Wed Aug 4 15:44:42 2010 | ||
| + | Check interval: 5184000 (2 months) | ||
| + | Next check after: Sun Oct 3 15:44:42 2010 | ||
| + | ...cut... | ||
| + | </code> | ||
| + | |||
| + | And change them using the same command: | ||
| + | <code> | ||
| + | # tune2fs -c0 -i0 /dev/sda2 | ||
| + | tune2fs 1.38 (30-Jun-2005) | ||
| + | Setting maximal mount count to -1 | ||
| + | Setting interval between checks to 0 seconds | ||
| + | </code> | ||
| + | |||
| + | Setting explanation: | ||
| + | * -c max_mounts_count | ||
| + | * -i interval[d|m|w] | ||
| + | |||
| + | Now the settings look like this if you would issue tune2fs -l <device> again: | ||
| + | <code> | ||
| + | Maximum mount count: -1 | ||
| + | Last checked: Wed Aug 4 15:44:03 2010 | ||
| + | Check interval: 0 (<none>) | ||
| + | </code> | ||
