Hi,
for some days I've been getting syslog messages which I now tracked down to
this assertion ("kernel BUG at fs/nfs/fscache.c:385!"):
/*
* Release the caching state associated with a page if undergoing complete
* page invalidation.
*/
void __nfs_fscache_invalidate_page(struct page *page, struct inode *inode)
{
struct nfs_inode *nfsi = NFS_I(inode);
struct fscache_cookie *cookie = nfsi->fscache;
BUG_ON(!cookie); <========== failing line 385
I must admit that I spent too much time recently on sysadmin things, so I am
not too eager to debug this, but I thought I should let you know, just in case
that this is something which really should not have happened.
I don't know what triggered it; I had been using fscache (on a 2.6.34 kernel)
successfully for (maybe exactly) two weeks now, and suddenly I got these
problems. (I stopped caching for now, in order to get other things done.)
Interestingly, it were always the same programs/actions which made problems,
possibly because they were accessing some specific files..
I also tried updating my kernel to 2.6.35, but that did not change anything.
(You might remember from my first posting that I am using NFS4 with Kerberos
etc.)
Have a nice day,
Hans
