NAME |
check -- file system consistency check |
SYNOPSIS |
check [ filesystem [[ blockno1 ... ] ] |
DESCRIPTION |
check will examine a file system, build a bit map of usedblocks, and compare this bit map against the bit map |
| |
| maintained on the file system. If the file system is notspecified, a check of both /dev/rf0 and /dev/rk0 is performed. Output includes the number of files on the filesystem, the number of these that are `large', the number of used blocks, and the number of free blocks. |
FILES |
/dev/rf0, /dev/rk0 |
| |
| |
SEE_ALSO |
find |
DIAGNOSTICS |
Diagnostics are produced for blocks missing, duplicated, andbad block addresses. Diagnostics are also produced for block |
| |
| numbers passed as parameters. In each case, the blocknumber, i--number, and block class (i = inode, x indirect, f free) is printed. |
BUGS |
The checking process is two pass in nature. If checking isdone on an active file system, extraneous diagnostics may |
| |
| occur. The swap space on the RF file system is not accounted forand will therefore show up as `missing'. |
