Internal filesystem saturation<BR />During boot, the system is attempting operations (fud.sh, rebuild processes), but fails due to lack of space. This can block firmware checks or system services.</P><P>2. System partition rebuild behavior<BR />The md_d10/md_d12/md_d16 rebuild messages suggest the system is trying to recover internal RAID partitions. If space is exhausted, these processes may not complete properly.</P><P>3. Possible causes<BR />- Excessive log accumulation<BR />- Incomplete upgrade or firmware process<BR />- Corruption or abnormal growth in system partitions</P><P>4. Next steps<BR />As mentioned, opening a support case is the right approach, since root-level access is required.</P><P>However, if console/root access is available, it may be useful to:<BR />- Check filesystem usage (df -h)<BR />- Identify large files under /var or tmp<BR />- Review if any upgrade or patch process was interrupted</P><P>In similar cases, cleanup or repair of internal partitions was required, which is typically handled by HPE support.</P><P>Regards,<BR />Carlos Parra Solano<BR />HPE Master ASE Storage</P> Wed, 25 Mar 2026 20:58:22 GMT https://community.hpe.com/t5/hpe-nimble-storage-solution/controller-nimble-af40-reboot-loop-and-cannot-join-arrray/m-p/7263626#M1490 controles 2026-03-25T20:58:22Z https://community.hpe.com/t5/hpe-nimble-storage-solution/controller-nimble-af40-reboot-loop-and-cannot-join-arrray/m-p/7264972#M1505 <DIV>&nbsp;</DIV><P><FONT face="arial,helvetica,sans-serif">The problem I encountered，cs3000，Insufficient storage space, unable to access the system after rebooting</FONT></P><DIV>&nbsp;</DIV><P>&nbsp;</P><P><FONT face="arial,helvetica,sans-serif">ERROR: md_d10 is not assembled</FONT></P><P>&nbsp;</P> Mon, 13 Apr 2026 13:28:25 GMT https://community.hpe.com/t5/hpe-nimble-storage-solution/controller-nimble-af40-reboot-loop-and-cannot-join-arrray/m-p/7264972#M1505 yeyang1 2026-04-13T13:28:25Z
