1929 | * Reason: |
1930 | Multiple clients A, B and C are attempting 'mkdir -p /mnt/a/b/c' |
1931 | |
1932 | 1 Client A is in the middle of mkdir(/a). It has acquired lock. |
1933 | It has performed mkdir(/a) on one subvol, and second one is still |
1934 | in progress |
1935 | 2 Client B performs a lookup, sees directory /a on one, |
1936 | ENOENT on the other, succeeds lookup. |
1937 | 3 Client B performs lookup on /a/b on both subvols, both return ENOENT |
1938 | (one subvol because /a/b does not exist, another because /a |
1939 | itself does not exist) |
1940 | 4 Client B proceeds to mkdir /a/b. It obtains entrylk on inode=/a with |
1941 | basename=b on one subvol, but fails on other subvol as /a is yet to |
1942 | be created by Client A. |
1943 | 5 Client A finishes mkdir of /a on other subvol |
1944 | 6 Client C also attempts to create /a/b, lookup returns ENOENT on |
1945 | both subvols. |
1946 | 7 Client C tries to obtain entrylk on on inode=/a with basename=b, |
1947 | obtains on one subvol (where B had failed), and waits for B to unlock |
1948 | on other subvol. |
1949 | 8 Client B finishes mkdir() on one subvol with GFID-1 and completes |
1950 | transaction and unlocks |
1951 | 9 Client C gets the lock on the second subvol, At this stage second |
1952 | subvol already has /a/b created from Client B, but Client C does not |
1953 | check that in the middle of mkdir transaction |
1954 | 10 Client C attempts mkdir /a/b on both subvols. It succeeds on |
1955 | ONLY ONE (where Client B could not get lock because of |
1956 | missing parent /a dir) with GFID-2, and gets EEXIST from ONE subvol. |
1957 | This way we have /a/b in GFID mismatch. One subvol got GFID-1 because |
1958 | Client B performed transaction on only one subvol (because entrylk() |
1959 | could not be obtained on second subvol because of missing parent dir -- |
1960 | caused by premature/speculative succeeding of lookup() on /a when locks |
1961 | are detected). Other subvol gets GFID-2 from Client C because while |
1962 | it was waiting for entrylk() on both subvols, Client B was in the |
1963 | middle of creating mkdir() on only one subvol, and Client C does not |
1964 | "expect" this when it is between lock() and pre-op()/op() phase of the |
1965 | transaction. |
