| |
Hi all,
I have a question about ext3 write activity.
I am considering using an ext3 fs on a CompactFlash disk for my data-logging application (power can disapear anytime). The quantity & frequency of the data logged itself is not a problem at all considering flash wear.
But I'm a bit worried about the kernel/ext3 doing regular writes by itself even when there are no userspace writes. (worries are partially caused by memories from long time ago about idle laptop doing regular writes on disk).
Anybody out there who knows how this works ?
Can I use an ext3 fs without having regular "automatic" writes to the device it is located on ? (and thus not destroy my CompactFlash devices !)
greetings, Rob van Nieuwkerk
PS1: of course nothing from userspace should write frequently to the fs, and if there is regular read-activity the fs should be mounted with "noatime")
PS2: yes, I know that jffs exists - 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/
