syncing disks... 54 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 giving up on 1
I am referring to the message when the code in kern_shutdown.c in bsd
4.10 is called at the time of boot() system call
My understanding is that this message tells us that 1 buffer from the
buffer cache was not successfully flushed to disk, since the last call to
sync(). Is that right? In that case what happens to this buffer? Is it
discarded and assume that fsck will fix this on reboot?
Since the syncer process runs periodically, can this error message be
avoided if we wait long enough to guarantee flushing to disk (I have tried
with DELAYS upto 30 seconds but I still get the error sometimes).
I am actually trying to use this same code at a different point in time
(not during shutdown, but to take a checkpoint), so I am not sure if that
contributes to this error message?
