Kirk McKusick c3046779b2 Optimize operations on UFS/FFS filesystems with bad cylinder group(s). ... If a UFS/FFS filesystem develops a broken cylinder group (which is usually detected when its check hash fails), that cylinder group will not be usable until the filesystem has been unmounted and fsck has been run to repair it. On the first attempt to to allocate resources from the broken cylinder group, its available resources are set to zero in the superblock summary information. Since it will appear to have no resources available, no further calls will be made to allocate resources from it. When resources are freed to the broken cylinder group, the resource free routines will find the cylinder group unusable so the resource will simply be discarded and thus will not show up in the superblock summary information until they are recovered by fsck.
