== sanity-compr test 2030: handle 16MB compressed RPC with many fragments ========================================================== 16:18:56 (1789071536)
Setting server brw_size to 16MB to support 16MB RPCs...
obdfilter.lustre-OST0000.brw_size=16
obdfilter.lustre-OST0001.brw_size=16
Forcing client reconnection to negotiate new brw_size...

Stopping client oleg359-client.virtnet /mnt/lustre (opts:)
Starting client: oleg359-client.virtnet:  -o user_xattr,flock 192.168.203.159@tcp:/lustre /mnt/lustre
Verifying negotiated max_brw_size on all OSTs...
SUCCESS: All OSTs negotiated 16MB brw_size

SUCCESS: All client parameters set correctly
Creating 16MB file
16+0 records in
16+0 records out
16777216 bytes (17 MB, 16 MiB) copied, 0.603554 s, 27.8 MB/s
Created 16MB file, size verified: 16777216 bytes
Calculating original file checksum...
Original MD5: 6600900fa073a02a352fb97ac7838566
CRITICAL TEST: Reading file to verify extent size limiting...
Without the fix, this would crash with  LASSERT(data->erd_page_count > 0)
SUCCESS: File read completed in  seconds without crash!
Data integrity verified: MD5 checksums match
Additional test: copying file...
Testing write operations on existing file...
All operations completed successfully!
The extent size limiting fix prevented the LASSERT crash
