MY'STORY

The MOVE Fire

This is a personal recollection on the Move fire on May 13, 1985 Philadelphia police fired thousands of rounds at the MOVE house, city officials approved dropping an explosive device on the roof, the resulting fire was allowed to burn, 11 people—including five children—died, and 61 homes were destroyed. Philadelphia City Council later called it a “brutal attack carried out by the City of Philadelphia on its own citizens” and acknowledged that no individual faced criminal consequences for the bombing. One timeline correction worth preserving for the BHP record: the major previous MOVE-police confrontation was August 8, 1978, about seven years before the bombing, not a year or two earlier. Officer James Ramp was killed, other police and firefighters were wounded, nine MOVE members were later convicted, and television cameras recorded police beating Delbert Africa during his arrest. The 1985 MOVE Commission later specifically criticized city planners for failing to adequately use lessons from that 1978 confrontation. And that actually strengthens the point you’re making: 1985 did not happen without precedent or institutional memory. There had already been a deadly confrontation with MOVE, years of conflict, negotiations and police involvement before Osage Avenue.

Hierarchical File System (IBM MVS)

HFS
DeveloperIBM
Full namez/OS Hierarchical File System
Introduced1993 with DFSMS/MVS Version 1.2 for MVS/ESA
Other
Supported
operating systems
included in z/OS (until 2.5), all releases of OS/390, and MVS/ESA V5R1 and higher (optional for V4R3)

IBM's Hierarchical File System (HFS) is a POSIX-style hierarchical file system[1] for the MVS/ESA/SP through z/OS operating systems.

IBM introduced HFS on February 9, 1993 in MVS/ESA System Product Version 4 Release 3 OpenEdition[2][3] with DFSMS/MVS Version 1 Release 2[4] for 3090 mainframes. On April 6, 1994, IBM introduced MVS/ESA System Product (MVS/ESA SP) Version 5 Release 1,[5] which included MVS OpenEdition (MVS-OE) with HFS as a standard component. IBM continued providing HFS through z/OS 2.4 for z System mainframes.

IBM functionally stabilized HFS starting with z/OS 1.7, in 2005.[6] The z/OS File System (zFS) was released as the higher performance successor to HFS in 1995, and IBM recommended migration from HFS to zFS. Following the release of zFS, z/OS releases included a tool, BPXWH2Z, to convert HFS to zFS.[7]

IBM dropped the use of HFS in z/OS 2.5, in 2021.[6]

ZFS (z/OS file system)

z/OS File System (zFS) (official name: z/OS® Distributed File Service zSeries® File System) is a POSIX-style hierarchical file system for IBM's z/OS operating system for z System mainframes, a successor to that operating system's HFS. zFS technology was first released in 1995 as the Local File System, a lower layer of the DCE Distributed File System. It was available on MVS/ESA V5R2.2 and all OS/390 releases. DFS/LFS was provided as a part of the DCE feature, not part of the base operating system. As a separate feature (outside the DCE feature), zFS was initially released for z/OS as PTFs (patches) for z/OS 1.2, with backports available for z/OS 1.1 and OS/390 2.10. Beginning with z/OS 1.3, zFS is included as a standard feature and is being actively developed.

MVS

Multiple Virtual Storage (MVS) is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.
