File System Panics When Cluster File System is Full (4808748)

Problem Summary: When a cluster file system is full, there are instances where the filesystem might panic with one of the following messages: 1)

assertion failed: cur_data_token & PXFS_WRITE_TOKEN or PXFS_READ_TOKEN

or 2)

vp->v_pages == NULL

. These panics are intended to prevent data corruption when a filesystem is full.

Workaround: To reduce the likelihood of this problem, use a cluster file system with UFS as far as possible. It is extremely rare for one of these panics to occur when using a cluster file system with UFS, but the risk is greater when using a cluster file system with VxFS.
