Topic: RAID fsck

[Thorsten Dunker]

Hi all,

cause SME doesn´t support a journaling filesystem at the moment
my question is if it´s more secure to install on software raid.
after resetting my testserver 5 times during boot time the filesystem
crashs. but what happens if i replace the crashed harddisk with the
second from the raid. is this disk crashed too?

tia and greetings
thorsten

There is no link between RAID and fs.
And while a journaled fs will save the fs, it doesn't necessarly save your data if you reset the server while operating.
1. Use an UPS to protect against power failures and spikes
2. Use RAID to protect against an hardware failure
3. Use journaling to save from long fsck in case of problems (not on sme at the moment)
