dmraid: dmraid (Device-mapper RAID tool and library)
- Summary
- DMRAID supports RAID device discovery, RAID set activation and display of
properties for ATARAID on Linux >= 2.4 using device-mapper.
Changelog
- * Tue Mar 15 18:00:00 2005 Heinz Mauelshagen <heinzm{%}redhat{*}com> 1.0.0.rc6.1-3_RHEL4_U1
- VIA metadata format handler
- added RAID10 to lsi metadata format handler
- "dmraid -rD": file device size into {devicename}_{formatname}.size
- "dmraid -tay": pretty print multi-line tables ala "dmsetup table"
- "dmraid -l": display supported RAID levels + manual update
- _sil_read() used LOG_NOTICE rather than LOG_INFO in order to
avoid messages about valid metadata areas being displayed
during "dmraid -vay".
- isw, sil filed metadata offset on "-r -D" in sectors rather than in bytes.
- isw needed dev_sort() to sort RAID devices in sets correctly.
- pdc metadata format handler name creation. Lead to
wrong RAID set grouping logic in some configurations.
- pdc RAID1 size calculation fixed (rc6.1)
- dos.c: partition table code fixes by Paul Moore
- _free_dev_pointers(): fixed potential OOB error
- hpt37x_check: deal with raid_disks = 1 in mirror sets
- pdc_check: status & 0x80 doesn't always show a failed device;
removed that check for now. Status definitions needed.
- sil addition of RAID sets to global list of sets
- sil spare device memory leak
- group_set(): removal of RAID set in case of error
- hpt37x: handle total_secs > device size
- allow -p with -f
- enhanced error message by checking target type against list of
registered target types
- * Thu Dec 9 18:00:00 2004 Heinz Mauelshagen <heinzm{%}redhat{*}com> 1.0.0.rc5f
- added NVidia metadata format handler (#130324)
- quorate SIL metadata copies
- partition name suffix to make GRUB happy
- sorting order of stacked subset enhanced
(RAID10; hpt37x, hpt45x, lsi, nvidia and sil)
- started event methods implementation in metadata format handlers
- output linefeed to .offset files for better readability (-r -D)
- use /sys/block/*/removable to avoid acessing removable devices
- display of spare devices with -r -c...
- enhanced spare device handling
- '-h' option doesn't need to stand alone any more
- -s displays top level sets only. "-s -s" shows subsets as well.
- -f allows partial qualification of format names now
(eg, "dmraid -f hpt -r" will search for hpt37x and hpt45x formats)
- make suffix in hpt45x set names numeric
- HPT37x metadata format handler RAID10 grouping logic
- HPT37x/HPT45x avoid devision by zero bug
in case ->raid_disks is zero for spares
- avoid devision by zero bug in case of stride = 0
- SIL device names / checksums
- calc_total_sectors() on unsymmetric mirrors
- perform() could return an error without releasing a lock
- * Fri Nov 26 18:00:00 2004 Heinz Mauelshagen <heinzm{%}redhat{*}com> 1.0.0.rc5f
- specfile cleanup
