Re: dmraid 10.0.0rc13 crashes with ICH7

I must warn you that all these new tests and results have been done after SATA RAID has been DISABLED on bios and installed FC6 with the "nodmraid" option. http://www.latinsud.com/ddf1-HP_ML310-ICH7.tar.bz2 After all that I've also been playing with source code, cleaned up code and compiled with debugging: /* Find the offset for this config/drive. */ static uint64_t get_offset(struct ddf1 *ddf1, struct ddf1_config_record *cr,                            struct ddf1_phys_drive *pd) {         uint64_t * kk;         int i = get_offset_entry(ddf1, cr, pd);         if (i < 0)                 return pd->size;         else {                 kk=CR_OFF(ddf1, cr);                 return kk[i];         } } Then I got this: Starting program: /root/dmraid/1.0.0.rc13-mio/tools/dmraid -s Program received signal SIGSEGV, Segmentation fault. 0x0806687b in get_offset (ddf1=0x9f55768, cr=0x9f567d0, pd=0x9f56000) at format/ddf/ddf1.c:189 189                     return kk[i]; (gdb) bt #0  0x0806687b in get_offset (ddf1=0x9f55768, cr=0x9f567d0, pd=0x9f56000) at format/ddf/ddf1.c:189 #1  0x08068089 in group_rd (lc=0x9f54520, rs_group=0x9f58908, rd_group=0x9f54670) at format/ddf/ddf1.c:746 #2  0x0806831f in ddf1_group (lc=0x9f54520, rd=0x9f54670) at format/ddf/ddf1.c:817 #3  0x0805434f in dmraid_group (lc=0x9f54520, rd=0x9f54670) at metadata/metadata.c:657 #4  0x0805476c in group_set (lc=0x9f54520, name=0x0) at metadata/metadata.c:873 #5  0x0804bdb5 in build_sets (lc=0x9f54520, sets=0xbfd506ec) at toollib.c:69 #6  0x0804b96f in get_metadata (lc=0x9f54520, p=0x8073ce8, argv=0xbfd506ec) at commands.c:640 #7  0x0804baa7 in _perform (lc=0x9f54520, p=0x8073ce8, argv=0xbfd506ec) at commands.c:767 #8  0x0804bb7f in perform (lc=0x9f54520, argv=0xbfd506ec) at commands.c:787 #9  0x0804aa21 in main (argc=2, argv=0xbfd506ec) at dmraid.c:34 (gdb) print kk $1 = (uint64_t *) 0x9f969cc Where "kk" takes random values each execution.

Do you think we will be able to set it up using Fedora and dmraid, any advice? I might also try to update firmware. Thanks.

dmraid and Adaptec 1210SA

Hello, I've having trouble getting my new Adaptec card working in linux. I have installed the card, attached two blank drives, which I want to use in a RAID 1 mirror. (sda & sdb) I have been rather dissapointed to discover this is not a real RAID card but mostly software RAID, and the tool I should use is dmraid. The supplied linux driver is useless as it's a ".o" not a ".ko". I have setup the array in the HostRAID BIOS using the "build" option, even though the drives are blank. The array did appear at this stage, but only on one drive in a degraded state. I keep getting repeated messages from dmraid stating: "ERROR: asr: Invalid RAID config table checksum (0xF36 vs. 0x805) on /dev/sda" however google has no info on this error. diag using dmraid returned the following: root@Knoppix:~# dmraid -vvv -r /dev/sda WARN: locking /var/lock/dmraid/.lock NOTICE: skipping removable device /dev/hdd NOTICE: skipping removable device /dev/hdc NOTICE: /dev/sda: asr discovering NOTICE: asr: reading extended data on /dev/sda ERROR: asr: Invalid RAID config table checksum (0xF36 vs. 0x805) on /dev/sda NOTICE: /dev/sda: ddf1 discovering NOTICE: /dev/sda: hpt37x discovering NOTICE: /dev/sda: hpt45x discovering NOTICE: /dev/sda: isw discovering NOTICE: /dev/sda: jmicron discovering NOTICE: /dev/sda: lsi discovering NOTICE: /dev/sda: nvidia discovering NOTICE: /dev/sda: pdc discovering NOTICE: /dev/sda: sil discovering NOTICE: /dev/sda: via discovering No RAID disks and with names: "/dev/sda" WARN: unlocking /var/lock/dmraid/.lock root@Knoppix:~# dmraid -vvv -r /dev/sdb WARN: locking /var/lock/dmraid/.lock NOTICE: skipping removable device /dev/hdd NOTICE: skipping removable device /dev/hdc NOTICE: /dev/sdb: asr discovering NOTICE: asr: reading extended data on /dev/sdb ERROR: asr: Invalid RAID config table checksum (0xF36 vs. 0x805) on /dev/sdb NOTICE: /dev/sdb: ddf1 discovering NOTICE: /dev/sdb: hpt37x discovering NOTICE: /dev/sdb: hpt45x discovering NOTICE: /dev/sdb: isw discovering NOTICE: /dev/sdb: jmicron discovering NOTICE: /dev/sdb: lsi discovering NOTICE: /dev/sdb: nvidia discovering NOTICE: /dev/sdb: pdc discovering NOTICE: /dev/sdb: pdc metadata discovered NOTICE: /dev/sdb: sil discovering NOTICE: /dev/sdb: via discovering INFO: RAID device discovered: /dev/sdb: pdc, "pdc_jhegfcbhh", mirror, ok, 396484375 sectors, data@ 0 WARN: unlocking /var/lock/dmraid/.lock I then tried building the array again in the Adaptec BIOS, this time using the CLEAR array option.

dmraid -s size question

Hi, I noticed that the dmraid -s displays a size value in sectors that is less than the dmraid -r size value. What is this smaller size? on a 30GB drive /dev/hde with promise span metadata here are the sector size results: 60036480 dmraid -b sector size of /dev/hde 60036417 dmraid -r sector size of /dev/mapper/pdc_bibegjhbc 60036417 0x214 raid.disk_secs (dmraid -n /dev/hde) 60036417 0x224 raid.total_secs 60036352 dmraid -s what is this size? -James Free Movies 100's of Free Feature Length Films - Meet Friends, Watch Movies & Win! _______________________________________________ Ataraid-list mailing list Ataraid-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ataraid-list
