iam using ssd for caching other disks ( flashcache module ) if a power failure happened write operations will just stop suddenly and lead to bad sector due to incomplete cache back to devices ( sata disks ) so is there is a way to continue get cache from ssd to devices ( disks ) after server startup, as the cache already stored on ssd?
Many thanks in advance
I would like to have FlashCache cache my /var partition however I can't seem to get it to play nice upon bootup (IE: not really sure how to do it).
I'm not sure if I need to modify the initramfs/use DKMS or if I can do it in user-land during bootup. The issue I'm running into is /var mounts early and therefore the device is busy (whether it by generally by syslogd).
I'm positive this can be resolved by modifying the initramfs although I simply haven't fiddled with it enough to get it working.
They have instructions on how to boot your root partition however I'm not sure if these instructions would apply to my use case.
Any help / pointers in the right direction would be absolutely splendid.
